Abstract

In this paper we compute the one loop chiral-logarithmic corrections to all O(p⁴) counterterms in the three site Higgsless model. The calculation is performed using the background field method for both the chiral and gauge fields, and using Landau gauge for the quantum fluctuations of the gauge fields. The results agree with our previous calculations of the chiral-logarithmic corrections to the S and T parameters in 't Hooft-Feynman gauge. The work reported here includes a complete evaluation of all one loop divergences in an SU(2)\ifmmode×\else\texttimes\fiU(1) nonlinear sigma model, corresponding to an electroweak effective Lagrangian in the absence of custodial symmetry.
