Reliability of the Estimation of CP Asymmetries for Nonleptonic $B^0-{\bar{B}}^0$ Decays into Non-CP-Eigen states

Abstract

CP asymmetries for two-body-nonleptonic $B^0-{\bar{B}}^0$ decay into non-CP-eigen states are calculated using two different methods: (i) Bauer, Stech, and Wirbel factorization method to compute the decay amplitudes directly; (ii) using $B^0,{\bar{B}}^0$ decay amplitude ratios to avoid the direct computation of the decay amplitudes. The comparison of the results are made. The conclusion is presented.
