Abstract

We study the two-body weak decays of bottom-charm ($B_c$) and bottom-strange ($B_s$) mesons decay to a pseudoscalar meson (P) and an axial-vector meson (A) in CKM-favored and CKM-suppressed modes. We have obtained the form factors involving $B_c\to A_1^{1/2},A_1^{3/2}$ and $B_s\to A_1^{1/2},A_1^{3/2}$ transitions in the nonrelativistic quark model framework within the heavy quark symmetry constraints. The predictions of branching ratios for $B_c\to B_{(s)1}P$ and $B_c(B_s)\to D_{(s)1}P$ decays are presented. We find that the branching ratios of several decays are $\mathcal{O}({10}^{-2})\sim \mathcal{O}({10}^{-5})$.
