Phenomenology of non-custodial warped models

Article

Abstract

We study the effect of bulk fermions on electroweak precision observables in a recently proposed model with warped extra dimensions and no custodial symmetry. We find that the top-quark mass, together with the corrections to the \( Z{b_L}{\bar{b}_L} \) vertex and the one-loop contribution to the T parameter, which is finite, impose important constraints that single out a well defined region of parameter space. New massive vector bosons can be as light as ~ 1.5TeV and have large couplings to the tR quark, and suppressed couplings to the tL, bL and lighter quarks. We discuss the implications for searches of models with warped extra dimensions at the LHC.
