Description
I will give an overview of theoretical reasons for expecting a
possible violation of CPT symmetry in some models of Quantum
Gravity and then I will proceed to discuss experimental
signatures of such a violation. As CPT violation may be (but not
necessarily) linked to Lorentz Invariance Violation (LIV), a
seizable portion of the talk will be devoted to tests of Lorentz
symmetry violations, with emphasis on the case of neutral Kaons,
which is of direct relevance to this conference. In the second
part of the talk, I will discuss tests for CPT violation
due to decoherence in some quantum gravity models, and I will
explain how the latter can be disentangled from other effects,
such as LIV. In this respect, I will describe some possibly
unique (if exist) signatures of CPT violation through
decoherence in entangled states of neutral mesons, produced at
meson (such as Phi- or B-) factories, and I will discuss briefly
the relevant tests and sensitivities, including some theoretical
estimates on the order of magnitudes of such effects.
