Radion Flavor Violation in Warped Extra Dimension

High Energy Physics - Phenomenology 2013-05-30 v2

Abstract

We analyze the flavor violation in warped extra dimension due to radion mediation. We show that \Delta S=2 and \Delta B=2 flavor violating processes impose stringent constraints on radion mass, m_\phi and the scale \Lambda_\phi. In particular, for \Lambda_\phi ~ O(1) TeV, B_d^0-\bar{B}^0_d implies that m_\phi ~ 65 GeV. We also study radion contributions to lepton flavor violating processes: \tau -> (e,\mu) \phi, \tau -> e\mu^+\mu^- and B -> l_i l_j. We show that BR(B_s -> \mu^+ \mu^-) can be of order 10^{-8}, which is reachable at the LHCb. The radion search at LHC, through the flavor violation decays into \tau \mu or top-charm quarks, is also considered.
