kappa-Deformed Kinematics and Addition Law for Deformed Velocities

High Energy Physics - Theory 2007-05-23 v1

Abstract

In kappa-deformed relativistic framework we consider three different definitions of kappa-deformed velocities and introduce corresponding addition laws. We show that one of the velocities has classical relativistic addition law. The relation of velocity formulae with the coproduct for fourmomenta and noncommutative space-time structure is exhibited.
