A New Custodian for a Realistic Higgsless Model

Abstract

We present an example of a realistic Higgsless model that makes use of alternative $SU(2{)}_R$ assignments for the top and bottom quarks recently proposed by Agashe et al. which results in an enhanced custodial symmetry. Using these new representat ions reduces the deviations in the $Z{b}_{\ell }{\bar{b}}_{\ell }$ coupling to $\sim 4$ for a wide range of parameters, while this remaining correction can also be eliminated by varying the localization parameter (bulk mass) for $b_r$.
