Abstract: | We have studied some of the two body nonleptonic decays ofB meson in the context of heavy quark effective theory using factorization hypothesis. Treatinga
1 as a free parameter, we have obtained its value asa
1=0.822±0.045, by correlating the experimental and predicted branching ratio for
process. With this value ofa
1 the branching ratios obtained for other decay channels are in good agreement with the experiment. The decay constant ofD meson is extracted to be 280.82 MeV. Heavy quark spin symmetry has also been tested. |
