Phenomenology of non-custodial warped models

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 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 t R quark, and suppressed couplings to the t L , b L and lighter quarks. We discuss the implications for searches of models with warped extra dimensions at the LHC.
