Study of the b → dℓℓ transitions in the Standard Model and test of New Physics sensitivities

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