Abstract:

In the framework of the minimal SU(2)_L×SU(2)_R×U(1) theory, the possibility of large CP violating asymmetries in B_S decays is investigated. We show that a certain class of models where the CP symmetry is violated spontaneously and a relatively light W_R is allowed leads naturally to large CP asymmetries in the nonleptonic decays (∼20%) and in the semileptonic decays (∼20%) for a certain mass domain W_R. The decay modes B_s →D_s^*D_s^*, D_sD_s and ψφ will be promising ones for finding CP violation.
