thesis / dissertation description
The on-mass-shell renormalization prescription of electroweak theory is extended to account for shifts in the mass-shell. These shifts arise from dynamical contributions generated by the nonperturbative content of the vacuum to the quark self-energies. Upper limits for the value of the dimension-3 fermion-antifermion condensate are found by considering its contribution to the u-d mass difference and the strangeness-changing nonleptonic decays of the kaon. Dynamical generation of fermion masses under chiral gauge interactions is also examined by considering the coupling of light fermions to a heavy fermion-antifermion condensate.
