News on B→ K⁽*⁾νν in the Standard Model and beyond

الأصل · EN

An analysis of the rare B decays B→ K⁽*⁾νν is presented both within the SM and beyond. The SM predictions for the branching ratios are updated and uncertainties reduced. For the NP analysis both a model independent approach is used and concrete NP models are studied. The relations between b→ sνν and b→ sℓ+ℓ- transitions are analysed in detail.
