KK-number non-conserving decays: Signal of n=2 excitations of extra-dimensional models at the LHC

In the simplest universal extra-dimensional models Kaluza–Klein (KK) parity distinguishes the states with odd and even KK-number. We calculate the coupling of a 2n-level top quark to a top quark and the Higgs scalar (both n=0 states), absent at the tree level, which is mediated by strong interaction...
