New Physics constraints from optimized observables in B → K*μ+μ- at large recoil

B -> K*mu(+)mu(-) 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.
