The nonleptonic decays of b-flavored mesons to S-wave charmonium and charm meson states.

The detection of radially excited charmonium and charm meson states, and measurement of heavy meson decays, particularly B c + → J / ψ D s + and B c + → J / ψ D s ∗ + , by the LHCb and ATLAS Collaborations, have aroused a lot of theoretical interest in the nonleptonic decays of b-flavored mesons. In this paper, we study the exclusive two-body nonleptonic B ¯ 0 , B s 0 ¯ , B - and B c - -meson decays to two vector meson ( V 1 (n S) V 2 ) states. Assuming the factorization hypothesis, we calculate the weak-decay form factors from the overlapping integrals of meson wave functions, in the framework of the relativistic independent quark (RIQ) model. We find a few dominant decay modes: B - → D ∗ 0 ρ - , B 0 ¯ → D ∗ + ρ - , B s 0 ¯ → D s ∗ + ρ - , B - → J / ψ K ∗ - and B c - → J / ψ D s ∗ - with predicted branching fractions of 1.52, 1.40, 1.16, 0.46 and 0.27 (in % ), which are experimentally accessible. The predicted branching fractions for corresponding decay modes to excited (2S) states, obtained in O (10 - 3 - 10 - 4) lie within the detection accuracy of the current experiments at LHCb and Tevatron. Our predicted CP-odd fractions ( R ⊥ ) for color-favored B c -decays to two charmful states ( D ∗ D (s) ∗ ) are found significant as compared to similar decay modes of other b-flavored mesons.
