New Physics constraints from optimized observables in B -> K*ll at large recoil

Abstract

B -> K*ll angular observables have become a key ingredient in global model-independent analyses of b->s transitions. However, as experimental precision improves, the use of theoretically clean quantities becomes a crucial issue. Global analyses that use clean observables integrated in small bins are already a reality, opening up a new chapter in our quest for New Physics.
