Title: A new custodian for a realistic Higgsless model

Abstract

We present an example of a realistic Higgsless model that makes use of alternative SU(2){sub R} assignments for the top and bottom quarks recently proposed by Agashe et al. which results in an enhanced custodial symmetry. Using these new representations reduces the deviations in the Zb{sub l}b{sub l} coupling to {approx}4% for a wide range of parameters, while this remaining correction can also be eliminated by varying the localization parameter (bulk mass) for b{sub r}.
