摘要
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 Zb(L)(b) over bar (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 similar to 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.
