Analysis of the form factors of $B_c\to D^{(\ast )}$, $D_s^{(\ast )}$ and their nonleptonic decays

Bin Wu, Guo-Liang Yu, Zhi-Gang Wang +2

This article is devoted to calculating the form factors of $B_c\to D^{\ast }$, $B_c\to D$, $B_c\to D_s^{\ast }$ and $B_c\to D_s$ transitions in the framework of three-point QCD sum rul…
