B → K* ℓ+ ℓ- as a probe of Universal Extra Dimensions
Ferrandes, Rossella
Original · EN
We study some rare B decays induced by b → s transition within the Standard Model and in the Appelquist-Cheng-Dobrescu model, which is a New Physics scenario with a single universal extra dimension. In particular, we discuss the dependence on the radius R of the compactified extra-dimension of the branching ratio, the forward-backward asymmetry and the K* helicity distributions for the decay modes B → K* ℓ+ ℓ-, with ℓ-=e-,μ-, and the tau polarization asymmetries for the mode B → K* τ+ τ-.
