Description
Deformed relativistic kinematics, expected to emerge in a flat-spacetime limit of quantum gravity, predicts the Planck-scale violation of CPT symmetry. Deformations of the action of CPT are derived from the kappa-deformed Poincare algebra. This entails a subtle but measurable corrections to characteristics of time evolution, e.g. particle lifetimes or oscillations in two-particle states at high energy.We argue that using the muon lifetime or quark flavour oscillations we can bound $\kappa>10^{14}$ GeV at LHC energy and move this limit to $10^{16}$ GeV at future colliders.
