Quantum $\kappa$-deformations of D=4 relativistic supersymmetries

Abstract

We describe the quantum $\kappa$-deformation of super-Poincaré algebra, with fundamental mass-like deformation parameter $\kappa$. We shall describe the result in graded bicrossproduct basis, with classical Lorentz superalgebra sector which includes half of the supercharges.
