Abstract

A large number of observables can be constructed from differential decay rate based on the polarization of final state while considering decay of a neutral meson (P0orP¯0) to two vector particles. But all of these observables are not independent to each other since there are only a few independent theoretical parameters controlling the whole dynamics and therefore various relations among observables emerge. In this paper, we have studied the behaviour of observables for neutral meson decaying to two vectors in presence of T and CPT violations in mixing accompanied by both direct and indirect CP violations. We have expressed all of the fourteen unknown theoretical parameters for this scenario in terms observables only and constructed the complete set of thirty four relations among observables whose violation would signify the existence of some new Physics involving direct violation of CPT. In addition, using this formalism we have studied three special cases too: (a) SM scenario, (b) SM plus direct CP violation (c) SM plus T and CPT violation in mixing. © 2020, The Author(s).
