Production of charged meson in bottom hadron charmed decays and the effect of the finite width correction of the meson
We calculate the branching ratio of a bottom hadron decaying into a charmed
hadron and a charged meson within the QCD factorization approach. We
consider the effect of the finite width correction of the meson. Our
numerical calculation shows an obvious correction because of this effect. We
find that the finite width effect of the meson reduces the branching
ratios by about 9% to 11% for bottom meson decay channels:
, , and , and
increases the branching ratio by about 10% for
