Abstract:
Exclusive semileptonic decays based on b→s transitions have been attracting a lot of attention as some angular observables deviate significantly from the Standard Model (SM) predictions in specific q2 bins. B meson decays induced by other Flavor changing neutral current (FCNC), b→d, can also offer a probe to test new physics with an additional sensitivity to the weak phase in Cabibo-Kobayashi-Masakawa (CKM) matrix. We provide predictions for angular observables for b→d semileptonic transitions, namely B→ρℓ+ℓ−, Bs→K∗ℓ+ℓ−, and their CP-conjugated modes. Study of these decay modes will be useful to understand the deviations in b→s transitions.
