Double-Lepton Polarization Asymmetries in B->K_1 l^+ l^- Decay in Universal Extra Dimension Model

Abstract

Double-lepton polarization asymmetries for the exclusive decay B->K_1 l^+ l^- in the Universal Extra Dimension (UED) Model is studied. It is obtained that double-lepton polarization asymmetries are very sensitive to the UED model parameters. Experimental measurements of double lepton polarizations can give valuable information on the physics beyond the Standard Model (SM).
