Observables in b → sν ν Decays in the Standard Model and Beyond — •Michael Wick¹, Wolfgang Altmannshofer¹, Patricia Ball², Aoife Bharucha², Andrzej Buras¹, and David Straub¹ — ¹Physik-Department, Technische Universität München — ²IPPP, Department of Physics, University of Durham

The rare decay B→ K^*ν ν is considered as one of the important channels in B physics as it allows a transparent study of Z penguin effects in New Physics scenarios in the absence of dipole operator contributions and Higgs penguin contributions. We study all possible observables in B→ K^*ν ν and the related b to s transitions B→ K ν ν and B→ X_sν ν in the context of the Standard Model and various New Physics models. In particular we analyse the effect of right handed currents on these observables.
