talkabstract = "We construct $N=4$, $d=1$ superfield models, where superspace is based on the cosets of the supergroup $SU(2|1)$. It is not the standard $N=4$ supersymmetry, because it involves the mass parameter $m$. In the limit $m\rightarrow 0$ the standard one-dimensional $N=4$ Poincare superalgebra is recovered. We consider models associated with supermultiplets (1,4,3) and (2,4,2). We found interesting connections between these models and earlier works on nonlinear SUSY."
