Abstract

We reanalyze hadronic decays of B mesons to a pseudoscalar (P) and a tensor meson (Formula presented) or a vector meson (V) and a tensor meson, through a (Formula presented) transition. We discuss the possible large uncertainties to the branching ratios (BR’s) of the relevant modes, mainly arising from the uncertainties to the hadronic form factors for the (Formula presented) transition. The BR’s and (Formula presented) asymmetries for (Formula presented) and (Formula presented) decays are then calculated by using the form factors given in the ISGW2 model [the improved version of the original Isgur-Scora-Grinstein-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.
