Towards a global analysis of bs γ and bs+ decays — •Christoph Bobeth — Excellence Cluster Universe, Technische Universität München, München, Germany

Flavour changing neutral current decays mediated by bs γ and bs+ are indirect probes of new physics at or beyond the electroweak scale. They have been under investigation at the B-factories and the Tevatron during the last decade and are investigated currently at the LHC. Especially LHCb is expected to provide unprecedented accuracy and the measurement of new observables for the first time until the end of this year (2012). The theoretical predictions of inclusive and exclusive decays have also been refined allowing the first global analysis of these decays. In particular the angular distribution of BK* (→ K π)ℓ+ offers observables with reduced hadronic uncertainties whose potential role in a global anaylsis is studied. First results of model-independent fits are discussed.
