On the one hand, we have studied the charged current transitions of the B-meson which provide an important avenue for the clean extraction of the Cabibbo-Kobayashi-Maskawa (CKM) matrix elements (|Vub| and |Vcb|) which is very crucial for understanding the CKM structure of the Standard Model and for precise theoretical predictions of several observables and have tried to understand the source of the long-standing discrepancy between the inclusive and exclusive determinations by considering all possible ways of analyzing the available data. On the other hand, we have also studied the neutral current transitions (e.g. b - > sll and b -> dll) which are loop-suppressed in the Standard Model and thus offer potential probes of new physics at high energy scales.
