Deformed discrete symmetries

Understand

We construct discrete symmetry transformations for deformed relativistic kinematics based on group valued momenta.

• We focus on the specific example of kappa-deformations of the Poincare algebra with associated momenta living on (a sub-manifold of) de Sitter space.
• Our approach relies on the description of quantum states constructed from deformed kinematics and the observable charges associated with them.
• The results we present provide the first step towards the analysis of experimental bounds on the deformation parameter kappa to be derived via precision measurements of discrete symmetries and CPT.
