We re-analyze hadronic decays of B mesons to a pseudoscalar (P) and a tensormeson (T), or a vector meson (V) and a tensor meson, through a $b \to c$transition. We discuss possible large uncertainties to branching ratios (BR's)of the relevant modes, mainly arising from uncertainties to the hadronic formfactors for the $B \to T$ transition. The BR's and CP asymmetries for $B \toPT$ and VT decays are then calculated by using the form factors given in theISGW2 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 byan order of magnitude, compared to the previous results calculated within theISGW model.Comment: 22 pages, LaTex; minor clarifications included; to appear in Phys.
