Query: Particle-antiparticle asymmetry in a relativistic deformed kinematics   Relativistic deformed kinematics are usually considered as a way to capture
residual effects of a fundamental quantum gravity theory. These kinematics
present a non-commutative addition law for the momenta, so that the total
momentum of a multi-particle system depends on the specific ordering in which
the momenta are composed. We explore in the present work how this property may
be used to generate an asymmetry between particles and antiparticles through a
particular ordering prescription, resulting in a violation of CPT symmetry. We
study its consequences for muon decay, obtaining a difference in the lifetimes
of the particle and the antiparticle as a function the new high-energy scale
parameterizing such a relativistic deformed kinematics.
