B→ Xs γ in Warped Extra-Dimensions — •Jennifer Mutschall — Institut für Physik (THEP), Johannes Gutenberg-Universität, Mainz
Flavor-changing neutral currents like B→ Xs γ occure in the Standard Model (SM) only at loop level and are thus strongly sensitive to new physics. Moreover, thanks to the huge datasets collected at the B-factories, the experimental results for exclusive and inclusive decays of B-mesons have highly gained in precision during the last years. Therefore, strong constraints on extensions of the SM can be derived. In this talk I want to provide a leading-order calculation of the Wilson coefficient C7γ in the Randall-Sundrum Model. This calculation will be easily applicable to other models including copies of SM particles.
