| Abstract: | The two-body and
B¯meson decays emitting a pseudoscalar and a tensor meson in the final
state, using the factorization hypothesis have been investigated. We employ the
Isgur, Scora, Grinstein and Wise quark model to evaluate the form-factors
entering the decay amplitudes. Though many decay channels are available for B¯ and meson decays, the dominant
ones are: B¯ → D D 0, →DD+, B¯ → π¯ D0 and → π¯D+ which have the branching ratios (%) of the order of 10-2. To the
next order dominant decays are B¯→D0a , → D0 a /D0f2, B¯ → ƞcK¯ and → ƞc 0, B¯ → K¯D0/D¯D0 and B¯ → K¯D0 and → K¯D+/D¯D+, which have branching ratios (%) of the order of 10-3. We hope that the calculated
branching ratios are within the reach of current experiments.
