The study focuses on the two-body weak decays of bottom-charm and bottom-strange mesons to pseudoscalar and axial-vector mesons, with predictions of branching ratios. The branching ratios of several decays are found to be of similar orders of magnitude.
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 -> A(1)(1/2), A(1)(3/2) and B-s -> 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 -> B(s)1P and B-c(B-s) -> D(s)1P decays are presented. We find that the branching ratios of several decays are O(10(-2)) similar to O(10(-5)).
