Abstract

The $Υ (n S)$ $\to$ $B_{c} D_{s}$ , $B_{c} D_{d}$ weak decays are studied with the pQCD approach firstly. It is found that branching ratios $B r (Υ (n S) \to B_{c} D_{s})$ $\sim$ $O (1 0^{- 10})$ and $B r (Υ (n S) \to B_{c} D_{d})$ $\sim$ $O (1 0^{- 11})$ , which might be measurable in the future experiments.
