B → K^* µ⁺ µ⁻ – A Gold Mine of Observables to Probe New Physics — Wolfgang Altmannshofer¹, Patricia Ball², Aoife Bharucha², Andrzej Buras¹, •David Straub¹, and Michael Wick¹ — ¹T31, Physik-Department, Technische Universität München — ²IPPP, Department of Physics, University of Durham

The rare decay B → K^* (→ K π) µ⁺ µ⁻ is regarded as one of the crucial channels for B physics since its angular distribution gives access to many observables that offer new important tests of the Standard Model and its extensions. We study these observables in detail, identifying those with small to moderate dependence on hadronic quantities and large impact of New Physics. We point out a number of correlations between various observables which will allow a clear distinction between different New Physics scenarios.
