Searching for new physics in the angular distribution of B < inf > d < /inf > < sup > 0 < /sup > →φK* < sup > 0 < /sup > decay

Abstract

Motivated by the possible discrepancy between the observed CP asymmetry and that of the standard model expectation in the decay mode B 0→φKs, we study the corresponding vector vector decay mode B0 → φK*0. In order to obtain decisive information regarding the CP violation effect, we make an angular distribution analysis of the decay products, where both the outgoing vector mesons decay into two pseudo-scalars. Furthermore, we study the possible effects of new physics using the angular distribution observables. © 2004 The American Physical Society.
