New Heavy Quark Physics in the Strongly Yukawa Coupled Standard Model.

摘要

We show that for strong enough Yukawa coupling and weak gauge coupling the electroweak standard model quark finds it energetically advantageous to transform itself into a bound state in a Skyrme background. The mass of such a 'heavy' quark as also the heavy nucleon (a three quark color singlet composite) then decreases with the Yukawa coupling resulting in a maximum for the quark (nucleon) of 2 TeV (3 TeV). The three quark bound state, that is the nucleon, can be very strongly bound in this sheme in contrast to the weak binding mediated by QCD gluon exchange. As a candidate for new phenomenology at the SSC we find that the decay of a Delta like excited state of the heavy nucleon into W(sub L) plus heavy nucleon could provide an experimental signature of this scheme.
