Abstract

A new formulation on the lattice of a theory with a chiral fermion-scalar coupling and minimal field content is proposed. The arbitrariness in the regularization is used in order to decouple the replica fermions from the scalar. A continuum limit with just one fermion coupled to the scalar is obtained in perturbation theory and a Golterman-Petcher-like symmetry related to the decoupling of the replica fermions is identified.
