Electroweak Condensates at Standard Top Mass Values
R. Bonisch
Abstract
In the two Higgs doublet model, perturbativity breaks down below the Planck scale: For top mass values 170-180 GeV, the Yukawa coupling reaches the pole below 1000 TeV, if the ratio of vev's vu/vd is below 1. We discuss top condensate scenarios for 150 GeV < mtop < 200 GeV, showing that a version with two composite Higgses is a viable option. Within electroweak gauge extensions the second Higgs does not come with additional parameters, but is dictated by the symmetry.
