摘要
The experimental progress on flavor-changing neutral current decays governed by b -> sl(+)l(-) transitions has grown enormously due to the latest results of BaBar, Belle, CDF and LHCb. Especially the exclusive modes B -> K-(*())l(+)l(-), 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 Lambda(QCD)/m(b), 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 b -> sl(+)l(-) decays in combination with b -> s gamma and B-s -> mu(+)mu(-). 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.
