CPT violation and cascade decays
Abstract
In tagged cascade decays of the type P0 (P0-bar) -> M0 / M0-bar X -> f X there are two complex CPT-violating parameters: one in P0 - P0-bar mixing, the other one in M0 - M0-bar mixing. I analyze those decays and find that, in principle, the former parameter can be extracted from a careful comparison of their time dependences. CPT violation in M0 - M0-bar mixing, on the other hand, always appears entangled with ratios of decay amplitudes and cannot be extracted.
