Abstract

Analyzing an SU_L(2)-chiral gauge theory with external multifermion couplings, we find a possible scaling region where doublers decouple by acquiring chiral-invariant masses and ψ_R is free mode owing to the ψ_R-shift-symmetry, the chiral continuum theory of ψⁱ_L can be defined. This is not in agreement with the general belief of the failure of theories so constructed .
