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.truePredictions of angular observables for B s →k∗ and B →ρ in the standard model PREDICTIONS of ANGULAR OBSERVABLES for ...
