Effects of Ä-parity violation on CP asymmetries in Afi- & gt;/7 TT decay

Abstract

We study new CP violating effects in the A.b- > pTr decay mode that can arise in the minimal supersymmetric standard model with /{-parity violation. We estimate how much /î-parity violation modifies the standard model predictions for CP asymmetries within the present bounds. We find that in the R-parity violating model, the rate asymmetry (acp) is suppressed (about 10 times) and the asymmetry parameter A (or) is enhanced [approximately O(102) times] with respect to the SM predictions. ©2001 The American Physical Society.
