Constraining New Physics with Rare B and K Decays — •Martin Gorbahn — Institut für Theoretische Teilchenphysik, Universität Karlsruhe, D-76128 Karlsruhe
Rare decays of B and K mesons are highly suppressed in the standard model and therefore sensitive to new physics at or above the electroweak scale. I review the theory status of the decays B → Xs γ, B → Xs l+ l−, B → l+ l−, K → π ν ν, and K → π l+ l− and discuss how they constrain extensions of the standard model.
