Abstract

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