If the cosmological constant is non-zero waves are anharmonic in Friedmann-Robertson-Walker coordinates and although the amount of the anharmonicity is very small it gives noticeable effects for GW originating in extragalactic sources such as spiraling black hole binaries. The results indicate that the timing residuals induced by gravitational waves from such sources in PTA would show a peculiar angular dependence with a marked enhancement around a particular value of the angle subtended by the source and the pulsars, depending mainly on the actual value of the cosmological constant and the distance to the source. The position of the peak could represent a gauge of the value of the cosmological constant.

Even in the baryon spectrum, resonances like the $Lambda^+_c(2940)$ are a challenge for theoretical models. In this work we propose a theoretical explanation for this kind of phenomena as molecular structures coupled or not to $qbar q$ states. We work in the framework of a coupled channel calculation ~cite{Baru} generalized to include several meson-antimeson channels, several $qbar q$ states below and resonances above threshold. The $qbar q$ states are found solving the Schr"odinger equation in the framework of the constituent quark model of Ref.~cite{Vijande}. This model includes pion exchanges between quarks which is very important to describe the $Dbar D$ and $D p$ interaction The meson-antimeson interaction is consistently obtained using the Resonating Group Method with these wave functions and interaction. Finally we couple the $qbar q$ states with the $qbar q qbar q$ states using the microscopic $^3 P_0$ model. In this calculation the well known X(3872) resonance appears as a $DD^*$ molecule coupled to a $chi_{c_1}(2P)$ $cbar c$ state. The original $chi_{c_1}(2P)$ acquires a significant $DD^*$ component and can be identified with the X(3940). In the $0^{++}$ sector we include in the calculation the $chi_{c0}(2P)$ $cbar c$ state and the $DD$, $J/psiomega$, $D_sD_s$ and $J/psiphi$ meson-antimeson states. We find two states which can be identified with the $X(3915)$ and with the sometimes called $Y(3940)$. In the $1^{--}$ sector we obtain one new molecular state that could be assigned to the $G(3940)$ with an important dressing of the well established $psi(4040)$ and $psi(4160)$. Physical consequences of this dressing are discussed. Our results shows a new phenomenology in the charmonium spectrum which may constitute a challenge for more fundamental descriptions like ADS/CFT correspondence. However these new structures not only appear in the charmonium spectrum but can also occur in the baryon sector. We have extended the calculation to $DN$ and $BN$ molecules. We have identified the $Lambda_c(2940)^+$ baryon as a $J^P=frac{3}{2}^-$ $D^*N$ molecule ~cite{PLB}. We have study the decay channels $Lambda_c(2940)^+rightarrow D^0p$, $Lambda_c(2940)^+rightarrow D^+n$, $Lambda_c(2940)^+rightarrow Sigma_c^{++} pi^-$, $Lambda_c(2940)^+rightarrow Sigma_c^{+} pi^0$ and $Lambda_c(2940)^+rightarrow Sigma_c^0 pi^+$. The obtained widths of the $D^0p$ and $D^+n$ decay channels are of the order of the experimental data whereas the contributions of the $Sigma_cpi$ channels are negligible. The predicted total width agrees with experimental data . Moreover we predict in the same model the existence of new resonances in the $BN$ $DDelta$ and $BDelta$ channels with a relatively small width which can be discovered at LHCb in the near future. begin{thebibliography}{99} bibitem{Baru} V.

They are compared with cor- responding models in the frame of Friedmann-Robertson-Walker cosmology. For constraining the parameters of the models considered, recent observational data, including SNIa apparent magnitude measurements, baryon acoustic oscillation results, Hubble parameter evolution data and matter density perturbations are used. Also, explicit formulas of the so-called state-finder parameters in teleparallel theories are found that could be useful to test these models and compare Loop Quan- tum Cosmology and Brane Cosmology. The conclusion is reached that a joint analysis as the one developed here allows to estimate, in a very clear way, possible deviation of our cosmology from the standard Friedmann-Robertson-Walker one.

In practice, the last problems arise in the calculations using a large model configuration space. The extended RPA (random phase approximation) theories are analyzed here from the point of view of these problems. Two kinds of such theories are considered: the quasiparticle-phonon coupling model within the time-blocking approximation and the second RPA. It is shown that stability is ensured by making use of the subtraction method proposed previously (generalized Thouless theorem). The spurious states are eliminated with the help of a combination of the subtraction method and the projection technique. These results are illustrated by the calculations of the low-lying states in 208-Pb.

Comments: The investigation of neutrino properties is one of the most active fields of research in current high-energy physics. The existence of neutrino masses and mixing imply that non-trivial neutrino electromagnetic properties are plausible and experimentalists and theorists are eagerly looking for them. The theoretical and experimental study of neutrino electromagnetic interactions is a powerful tool in the search for the fundamental theory beyond the Standard Model. Moreover, the electromagnetic interactions of neutrinos can generate important effects, especially in astrophysical environments, where neutrinos propagate for long distances in magnetic fields both in vacuum and in matter. In the proposed talk, after a derivation of all the possible types of electromagnetic interactions of Dirac and Majorana neutrinos, I discuss their effects in terrestrial and astrophysical environments and the corresponding experimental results. In spite of many efforts in the search of neutrino electromagnetic interactions, up to now there is no positive experimental indication in favor of their existence. However, during recent years a reasonable progress has been achieved in obtaining new (more stringent) constraints on the upper bound of the neutrino effective magnetic moment. It is expected that in one-two years from now a new range for the neutrino magnetic moment will become accessible for investigations in terrestrial experiments. ---------------------------------------------------------------------- Registration from Prof Santiago Noguera Universidad de Valencia; Valencia, Spain Visa: yes; Transfer: Talk in section : Comments: Visa details: Full name:Santiago Noguera Puchol Date of birth:03 - 08 - 1954 Citizenship:Spain Passport number:AAD737360 Passport issue date:09 -05- 2011 Passport expire date:22 - 06 - 2014 Official workplace and position:Universidad de Valencia / Professor Work address:Dr. Moliner, 50 // 46100 Burjassot (Valencia) // Spain Dates of visit:15 - 09 - 2013 // 15 - 10 - 2013 ---------------------------------------------------------------------- Registration from Prof Stepan Sidorov Bogoliubov Laboratory of Theoretical Physics; Dubna, Russian Federation Visa: ; Transfer: Talk in section A - Particle physics: Comments: ---------------------------------------------------------------------- Registration from Prof Boris Ermolaev Ioffe Institute for Physics and Technology; St. Petersburg, Russia Visa: ; Transfer: Talk in section A - Particle physics: Relations between collinear and k_T -factorizations Collinear and $k_T$- factorizations were introduced from different theoretical grounds, applied to different evolution equations and look totally unrelated to each other.

Kant Baltic Federal University; Kaliningrad, Russia Visa: ; Transfer: Talk in section C - Gravitation and cosmology: Equation-of-state formalism for dark energy models on the brane and the future of brane universes Brane dark energy cosmologies, leading to various possible evolutions of our universe, are investigated. The discussion shows that while all these models can be made arbitrarily close to the standard CDM cosmology at present, their future evolutions can be very dierent, even diverge with time in a number of ways. This includes asymptotic de-Sitter evolution, Little Rip with dissolution of bound structures, and various possible singularities, as the Big Rip, a sudden future singularity (Type II), and Type III and Type IV cases. Specifically, the interesting eects coming from the brane tension are investigated. Thus, it is shown that the Little Rip occurs faster on the brane model than in usual FRW cosmology. And in the asymptotic de-Sitter regime the in uence of the brane tension leads to a deviation of the value of the eective cosmological constant from that corresponding to ordinary dark energy. As a consequence, the value of the inertial force from the accelerating expansion can greatly exceed the corresponding inertial force in ordinary cosmological models.

Along with the long-range contribution, originating from the fluctuation in the number of strings, the short-range contribution, originating from the correlation between multiplicities produced by a single emitter is also taken into account. It is shown that the presence of the correlations between particles produced by one string turns the strings into non-poissonian emitters. The dependencies of the correlation coefficient on the rapidity and azimuthal acceptance of the windows and on the corresponding gaps between windows are studied. It is shown that the analysis of these dependencies enables to separate the contributions of two above mechanisms. The connection of the FB multiplicity correlation coefficient with double inclusive cross section and two-particle correlation function is also traced. The suitable observables are proposed.

At small $mu$ in the $r$-vacua, where $r$ quarks condense the low energy theory has $U(r)times U(1)^{N-r}$ gauge group. We consider the so called zero vacua which are present at $r < (N_f-N)$ and show that at large $mu$ the low energy physics in these vacua can be described in terms of weakly coupled infrared-free $mu$-dual theory with $U(N_f-N)$ gauge group. In this theory $r$ quarks condense triggering confinement of monopoles. We compare $mu$-dual theory in zero vacua with Seiberg’s dual and find a perfect match. This match reveals the physical nature of Seiberg’s dual quarks. They turn out to be the ordinary quarks of the original theory rather then monopoles. We also review the phase structure of N=1 QCD at large $mu$.

These calculations are continuation of our investigations of nuclei with extreme neutron excess [1, 2]. Our calculations are based on the Hartree–Fock (HF) method with Skyrme forces (SkM*, SkI2, SLy4, Ska, SkP) taking into account axial deformation and the BCS pairing approximation. It is shown that the isotone chains with the neutron numbers N = 32, 58, 82, 126, 258 form the peninsulas of nuclei beyond the neutron drip line which are stable against one and sometimes two neutrons emission. The stability of the considered isotones is connected with full filling of neutron sub-shells with large angular momentum and with intrusion of corresponding neutron levels into the region of discrete bound states. The localization of the peninsulas of stability in the (N, Z) space takes place at the same values of N = 32, 58, 82, 126, 258 irrelatively the type of Skyrme forces. It is found that the size of the peninsulas is sensitive to the choice of Skyrme forces and the most extended peninsulas appear with the SkI2 set. Our results for long isotope chains of Zr and Gd up to the neutron drip line are compared with the Hartree-Fock- Bogoliubov calculations [3]. For some neutron rich nuclei with magic neutron numbers we have analyzed the potential energy curve as the function of the mass quadrupole moment E(Qm) through the constrained HF. It is shown that for N = 258 and Z ≥ 124 the superdeformed shapes of neutron and proton density distributions can correspond to ground state.

Such a crossing is made possible by certain transformations of matter properties. Some of these cosmological evolutions involving tachyons are compatible with SNIa data.

The combined data analysis proves that DE models under consideration are as consistent as $Lambda$CDM model. We demonstrate that growth of matter density perturbations may occur at sufficiently small background density but still before the possible disintegration of bound objects (like clusters of galaxies, galaxies, etc) in Big Rip, type III singularity, Little Rip or Pseudo-Rip universe. One can rewrite the dark energy EoS (ref{EoS-0}) in the following form: $p_{D}=-rho_{D}-g(rho_{D}),$ where $g(rho_{D})$ is some function. We study the following two class of models. The natural choice is $g(rho_{D})=alpha^{2}rho_{D0}left(frac{rho_{D}}{rho_{D0}}right)^{beta}$ where $alpha$ and $beta$ are dimensionless constants. If $beta=1$ we have ordinary phantom energy model with constant EoS parameter $w=-1-alpha^{2}$. For various $beta$ the model describes three types of future universe evolution: (a) Little Rip if $betaleq 1/2$, (b) Big Rip if $1/21$. The another interesting class of DE models is given by the equation $g(rho)=alpha^{2}rho_{D0}left(1-frac{rho_{D}}{rho_{f}}right)^{beta}, quad 01/2$.

The universe begins to evolve when, by quantum tunneling, the scalar field decays into a state of true vacuum. The emergent universe models are interesting since they provide specific examples of nonsingular inflationary universes.

It belongs to a new class of dual (string) models to be out of usual approaches. In this talk the description of baryons is considered. The meson-baryon interaction vertex is formulated. While classical string models with linear Regge trajectories inevitably lead to fermions of equal mass to be degenerated in parity, this model can eliminate this degeneration without violating superconformal symmetry.

The main attention will be devoted to the analysis of this data in the framework of multipomeron exchange model with collectivity (in a form of string fucion) and in PYTHIA event generator with color rconnection effects, both leading to the prediction of long-range pT-Nch correlations. The results are discussed pointing at the possibility of selection at the LHC energies of specific, "very central" pp collisions, characterized by the maximal energy density.

For studying fluctuations and searching delicate effect it is necessary to determine precisely measurement`s parameters (to fix the centrality classes) when the observable`s fluctuation is minimal. This work is connected with heavy-ions experiments in CERN at LHC energies and proposes the method of estimating the centrality classes where the fluctuations are minimized based on the analysis of RHIC experiments (WA97 [1], WA98 [2]). The main goal of this work is minimization of trivial fluctuations of observables by determination of the centrality classes width influence on the fluctuations of observables. For that purpose the Monte-Carlo generator of Pb-Pb collisions at 2,76TeV was created based on Glauber Model. We consider MC simulations due to the possibility of extraction of the information about impact parameter and number of nucleons participated in collisions. Using connection between multiplicity and number of nucleons participated in the collision we can evaluate the multiplicity which is measured on the experiments. This data makes the distinctions for different classes of centrality evident. We compared two methods of determination of centrality classes by impact parameter and multiplicity. Analysing the distribution of number of participated nucleons (Npart) in different centrality classes we can evaluate the value of RMS (root mean square) and mean value of Npart in each centrality class with the different widths. As a result, for all values of multiplicity and the impact parameter including the central and peripheral collisions the value of centrality selection bins was determined in percentage wise of widths in the minimum bias cross section where the fluctuations of the observable values are minimized. Using this method one can make analysis of the reconstructed data for different experiments of NN collisions at high energy (like ALICE [3]) to determine conditions where the observables fluctuations will be minimized.

Comments: ---------------------------------------------------------------------- Registration from Prof Vladimir Kovalenko Saint Petersburg State University; Saint Petersburg, Russia Visa: ; Transfer: Talk in section : Long-range correlations in proton-nucleus collisions in MC model with string fusion The study of long-range correlations between observables in two rapidity windows was proposed [1] as a signature of the string fusion and percolation phenomenon. In the present work we calculate the correlation functions and coefficients for $p-Pb$ collisions in the framework of the Monte Carlo string-parton model, based on the picture of elementary collisions of color dipoles [2]. It describes pA and AA scattering without referring to the Glauber picture of independent nucleons collisions [3] and includes effects of string fusion [4]. Different types of correlations are considered: $n-n$, $p_t-n$, $p_t-p_t$, where n is the event multiplicity of charged particles in a given rapidity window and $p_t$ is their mean transverse momentum. The results, obtained in the present work for $p-Pb$ collisions, are compared with avaliable experimental results for $p_t-n$ correlations in one window [5] and further predictions are made. [1] N.S.

The underlying physical processes are generated in accordance with the model with independent strings as particle emitters. Some modifications of the underlying physics model of collisions are considered. Using this MC model comparison between forward-backward correlation and di-hadron analysis methods is performed.

It is considered a universe on brane filled with a single real scalar field $phi$. A rate of change for the field $dot{phi}$ is set as a function of the field $dot{phi}=U(phi)$. Using superpotential $W=1/2U^2+V(phi)$ we have a pair of equation. After its integration, we can get a full energy density $rho$ of the field, its potential $V$ and Hubble parameter $H$ as functions of the field $phi$. There are two models under consideration: $U(phi)=phi^{-s}$ (for different $s=mathrm{const}$) and $U(phi)=-k^2exp{(-phi/phi_s)}$ ($k=mathrm{const}$, $phi_s=mathrm{const}$).par The second part is dedicated to a study of inflation in a flat FRLW universe filled with a single real scalar field $phi$ by reduction of Friedman equations to Abel equation of $1^{mathrm{st}}$ kind. With given potential $V(phi)$ this method allows to get a rate of change for the field as function of $phi$ and derive an energy density of the field, its pressure, Hubble parameter as functions of $phi$. In some cases it is possible to get exact solutions for this parameters and scale factor as explicit functions of time or in a parametric form. Such case is, for example, the case of potential $V(phi)=C^2exp(kappasqrt{2}phi)$ ($C^2=mathrm{const}$, $kappa=pm1$). This potential gives several types of solutions, depending on sign of an integration constant in solutions of corresponding Able equation. But in general all this solutions is similar: a scale factor grows with acceleration from finite value to infinity for infinite time (the energy density and pressure tend to zero), or it undergoes decelerated decrease to zero for finite time, or it goes down to zero, with deceleration at first and then with acceleration, for finite time (in last two cases it is possible to change a sign of time and get an increase from a finite value to infinity instead of a decrease).

The main physical reason for that is the energy gap of at least 500 GeV between the new found scalar and any ither new physics that could be probed at the LHC. Comments: Could I have some short talk about this topic? I that case, how long? Thank you very much in advance.

The relevant worldline supersymmetry is a deformation of the standard ${cal N}{=}4, d{=}1$ supersymmetry by a mass parameter $m$. As instructive examples we consider, at the classical and quantum levels, the models associated with the supermultiplets ({bf 1,4,3}) and ({bf 2,4,2}) and find out interesting interrelations with some previous works on non-standard $d{=}1$ supersymmetry. In particular, the $d{=}1$ systems with ``weak supersymmetry'' are naturally reproduced within our $SU(2|1)$ superfield approach as a subclass of the ({bf 1,4,3}) models. Comments:
