Selfinteraction and mass in quantum field theory
Abstract
Qualitative implications of electroweak theory are reconsidered on the assumption that the unique source of fermion rest mass is selfinteraction via coupling to gauge fields. This implies small but nonzero mass for neutrinos, and suggests that successive fermion generations are distinct coupledfield eigenstates of a selfinteraction mass operator. For a scalar Higgs field, this mechanism can account for the SU(2) symmetry breaking of electroweak theory without a biquadratic selfinteraction. The implied Higgs particle mass could be very small, eluding any search limited to heavy particles.
