Nonuniversal relativistic kinematics

Carmona, J.M. (Universidad de Zaragoza) ; Cortés, J.L. (Universidad de Zaragoza) ; Romeo, B.

Resumen: We present a systematic derivation of the constraints that the relativity principle imposes between coefficients of a deformed (but rotational invariant) momentum composition law, dispersion relation, and momentum transformation laws, at first order in a power expansion of an ultraviolet energy scale. This work generalizes previous results of universal relativistic kinematics to the case of particle-dependent relativistic kinematics, which can have interesting phenomenological applications that we explore in the second part of the manuscript.
