Study of ${\rm Y}(nS)$ $\to$ $B_{c}P$ decays with perturbative QCD approach

Yueling Yang, Junfeng Sun, Yan Guo +3

With the potential prospects of the ${\rm Y}(nS)$ at high-luminosity dedicated heavy-flavor factories, the color-favored ${\rm Y}(nS)$ $\to$ $B_c\pi$, $B_{c}K$ weak decays are studied with t…
