Branching ratio and CP violation in Bs0 → K∗0K̄∗0 decay in the framework of QCD factorization

Abstract

We present an analytic calculation of Branching Ratio (BR) and Charge-Parity (CP) violating asymmetries of the [Formula: see text] meson decay into the two light vectors [Formula: see text] by calculating the helicity amplitude in the framework of quantum chromodynamics (QCD) factorization approach. We find the BR of [Formula: see text] which is in full agreement with the recent theoretical predictions and experimental measurements. We also calculate the direct CP violation, CP violation in mixing and CP violation due to interference which are [Formula: see text], [Formula: see text], and [Formula: see text], respectively.
