Query: Calculation of the Branching Ratio of $B^{-}\to h_{c}+K^{-}$ in PQCD   The branching ratio of $B^-\to h_c+K^-$ is re-evaluated in the PQCD approach.
In this theoretical framework all the phenomenological parameters in the
wavefunctions and Sudakov factor are priori fixed by fitting other experimental
data, and in the whole numerical computations we do not introduce any new
parameter. Our results are consistent with the upper bounds set by the Babar
and Belle measurements.
