Effects of Rparity violation on CP asymmetries in Λ_{b}>pπ decay
Abstract
We study new CP violating effects in the Λ_{b}>pπ decay mode that can arise in the minimal supersymmetric standard model with Rparity violation. We estimate how much Rparity violation modifies the standard model predictions for CP asymmetries within the present bounds. We find that in the Rparity violating model, the rate asymmetry (a_{cp}) is suppressed (about 10 times) and the asymmetry parameter A(α) is enhanced [approximately O(10^{2}) times] with respect to the SM predictions.
