Fermion Pair Production in SO(5) x U(1) Gauge-Higgs Unification Models
We compute fermion pair production cross sections in $e^+e^-$ annihilation in models of electroweak symmetry breaking in warped 5-dimensional space. Our analysis is based on a framework with no elementary scalars, only gauge bosons and fermions in the bulk. We apply a novel Green's function method to obtain an analytic understanding of the new physics effects across the parameter space. We present results for $e^+e^-\to b\bar b$ and $e^+e^-\to t\bar t$. The predicted effects will be visible in precision measurements. Different models of $b$ quark mass generation can be distinguished by these measurements already at 250 GeV in the center of mass.
