$B^{\ast}$ ${\to}$ $\bar{D}D$ decays with perturbative QCD approach

Abstract

The nonleptonic two-body B * → DD weak decays are studied phenomenologically with the perturbative QCD factorization approach. It is found that thes decays have branching ratios 10 −9 , and might be promisingly measurable at the running LHC and forthcoming SuperKEKB experiments in the future.
