Abstract: Abstract Extensions of the Standard Model featuring a warped extra dimension compactified on an S 1/ℤ2 orbifold, in which the fermions and gauge bosons live in the bulk of the fifth dimension, offer one of… read more here.

Abstract: We estimate contributions from Kaluza-Klein excitations of gauge bosons and physical charge scalar for the explanation of the lepton flavor universality violating excess in the ratios $\mathcal{R}(D)$ and $\mathcal{R}(D^*)$ in 5 dimensional Universal Extra Dimensional… read more here.

DOI: 10.1103/physrevd.97.115039
Abstract: We propose a new mechanism to produce a fermion mass hierarchy dynamically in a model with a singlet generation of fermions. A five dimensional gauge theory on an interval with point interactions (zero-width branes) takes… read more here.
