| dc.description.abstract | We have studied some of the two body nonleptonic decays of B meson in the context of heavy quark effective theory using factorization hypothesis. Treating a1 as a free parameter, we have obtained its value as a1 = 0.822 ± 0.045, by correlating the experimental and predicted branching ratio for B̄0 → D+π- process. With this value of a1 the branching ratios obtained for other decay channels are in good agreement with the experiment. The decay constant of D meson is extracted to be 280.82MeV. Heavy quark spin symmetry has also been tested. | |
