Abstract

After we have limited elements of the right-handed CKM matrix to satisfy the bounds for CP violation ɛ_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 χ² analysis is applied to B − ¯B mixing to constrain the right-handed CKM matrix elements. In (sin (2α), sin (2β)), (x_s, sin (γ)), (ρ, η), and (x_s, sin (2φ_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.
