Abstract

After we have limited elements of the right-handed CKM matrix to satisfy the bounds for CP violation epsilon_K in K meson systems, the right-handed charged current gauge boson W_R is shown to substantially affect CP asymmetries in B systems. A joint chi-squared analysis is applied to B-Bbar mixing to constrain the right-handed CKM matrix elements. In (sin(2alpha), sin(2beta)), (x_s, sin(gamma)), (rho-eta), and (x_s, sin(2phi_s)) plots in the presence of the W_R boson, we find larger allowed experimental regions that can distinguish this model from the standard model.
