We study the semileptonic decays involving the quark level transition , in the framework of the standard model (SM). We calculate the branching ratios and we define observables such as the ratio of branching fractions for different leptonic modes and , where for the same leptonic mode and we estimate their numerical values. We also study observables such as the differential branching ratio and forward-backward asymmetry and their implications.
