Predictions of angular observables for B s →k∗ and B →ρ in the standard model PREDICTIONS of ANGULAR OBSERVABLES for ... BHARTI KINDRA and NAMIT MAHAJAN

Exclusive semileptonic decays based on b→s transitions have attracted a lot of attention as some angular observables deviate significantly from the standard model (SM) predictions. B meson decays induced by other flavor changing neutral current (FCNC), b→d, can also offer a probe to new physics with an additional sensitivity to the weak phase in the Cabibbo-Kobayashi-Maskawa (CKM) matrix. We provide predictions for angular observables for b→d semileptonic transitions, namely Bs→K∗ + -, B0→ρ0+ -, and their CP-conjugated modes including various nonfactorizable corrections. For B0→ρ0+ - mode, B0-B0 mixing effects have been included and predictions are made for Belle and LHCb separately. Study of these decay modes will be useful in its own right and to understand the pattern of deviations in b→s transitions.
