Abstract

We investigate the B -> K-0(*)(1430)l(+)l(-) transition in the Applequist-Cheng-Dobrescu model in the presence of a universal extra dimension. In particular, we calculate double lepton polarization asymmetries and branching ratio related to this channel and compare the obtained results with the predictions of the standard model. Our analysis of the considered observables in terms of radius R of the compactified extra-dimension as the new parameter of the model show a considerable discrepancy between the predictions of two models in low 1/R values.
