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 Greens function method to obtain an analytic understanding of the new physics effects across the parameter space. We present results for e e− → b bbar and e e− → t tbar. 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.
