Hadronic decays of B involving a tensor meson through a b → c transition

We re-analyze hadronic decays of B mesons to a pseudoscalar (P ) and a tensor meson (T ), or a vector meson (V ) and a tensor meson, through a b → c transition. We discuss possible large uncertainties to branching ratios (BR’s) of the relevant modes, mainly arising from uncertainties to the hadronic form factors for the B → T transition. The BR’s and CP asymmetries for B → PT and V T decays are then calculated by using the form factors given in the ISGW2 model (the improved version of the original Isgur-ScoraGrinstein-Wise (ISGW) model). We find that the estimated BR’s of many modes are increased by an order of magnitude, compared to the previous results calculated within the ISGW model.
