Bounds on CPT and Lorentz violation from experiments with kaons

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

Possible signals for indirect CPT violation arising in experiments with neutral kaons are considered in the context of a general CPT- and Lorentz-violating standard-model extension. Certain CPT observables can depend on the meson momentum and exhibit sidereal variations in time. Any leading-order CPT violation would be controlled by four parameters that can be separately constrained in appropriate experiments. Recent experiments bound certain combinations of these parameters at the level of about 102010^{-20} GeV.
