Abstract
After incorporating all the available experimental data and the most up-to-date Lattice and light cone sum rule (LCSR) inputs on the form factors, we analyze the exclusive b → uℓνℓ and b → dℓℓ decays simultaneously. We have extracted the shapes of all the associated form factors using which we have provided predictions in the standard model for the branching ratios, direct CP asymmetries and isospin asymmetry for B → πℓℓ and various angular observables for B → ρℓℓ transitions. Also, we have tested the sensitivities of these observables towards physics beyond the standard model (BSM). For the B → ρℓℓ decays, we have defined tagged and untagged observables and predicted them in the SM and BSM. In the context of BSM, we have found some compelling information. The respective predictions in a few benchmark scenarios are given, which can be tested in the experiments at the LHCb and the Belle.
