Abstract

We study the effects of localization of the U(1)_Y gauge boson around the visible brane and the contributions of the Kaluza–Klein modes of Z bosons on the branching ratio of the lepton flavor violating τ→μν_īν_i decay. We observe that the branching ratio is sensitive to the amount of localization of the Z boson in the bulk of the Randall–Sundrum background.
