| dc.description.abstract | In this thesis, we rst study the lagrangian formulation of gauge theories, QED, Yang- Mills theory and the Glashow-Weinberg-Salam model for Electroweak interaction. We then, we use the framework of Bethe-Salpeter equation (BSE) under Covariant Instan- taneous Ansatz (CIA) to calculate the leptonic decays of B-meson. The structure of hadron-quark vertex function (^q) is obtained from BSE under CIA, while the structure of q qW vertex is obtained from GWS model for Electroweak interactions. We derive for- mulas for the decay constant fB of B-meson. We obtain the numerical values of the decay constant, fB of the B-meson as well as its decay width. Then the results are compared with existing experimental results | en_US |
