Study of $B_c$$\to$$J/\psi V$ and $B_c^{\ast }$$\to$${\eta }_{c}V$ decays within the QCD factorization

Qin Chang, Li-Li Chen, Shuai Xu

In this paper, we study the non-leptonic $B_c\to J/\psi V$ and $B_c^{\ast }\to {\eta }_{c}V$~$(V=\rho ,K^{\ast })$ weak decays in the framework of QCD factorization. In the evaluation, the form fac…
