Gauge created top quark condensate and heavy top
Abstract
The scalar interaction term of the top mode standard model can be generated by a gauge theory. It is emphasized that in this approach generalization to family space directly yields a heavy top quark while leaving all other quarks massless. By generating the new interaction from gauge extension to custodial SU(2), the standard model bound mtop < 200 GeV is pushed to mtop < 270 GeV, thereby significantly reducing the amount of finetuning required to match this number.
