Abstract
The experimental progress on flavor-changing neutral current decays governed by bâsâ+ââ transitions has grown enormously due to the latest results of BaBar, Belle, CDF and LHCb. Especially the exclusive modes BâK(â)â+ââ, which have the largest rates, provide a variety of observables which constrain non-standard interactions that would affect them beyond the Standard Model. The theoretical treatment, based on expansions in ÎQCD/mb, focuses on low- and high dilepton invariant mass regions. Notably, form factor symmetries guided the identification of optimized observables in both regions which have small form factor dependences and sensitivity to new physics. Current experimental results of rates and lepton forward-backward asymmetries allow for first global analysis of bâsâ+ââ decays in combination with bâsγ and Bsâμ+μâ. These analyses are now ready to be applied to include high-statistics results from LHCb and Super-Flavor factories within the next years and to profit from optimized observables.
