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.
