A Lattice Chiral Gauge Theory with Multifermion Couplings
Abstract
Analyzing an SUL(2)-chiral gauge theory with external multifermion couplings, we find a possible scaling region where doublers decouple by acquiring chiral-invariant masses and R is free mode owing to the R-shift-symmetry, the chiral continuum theory of iL can be defined. This is not in agreement with the general belief of the failure of theories so constructed .
