A Wilson-Majorana Regularization for Lattice Chiral Gauge Theories
arXiv:hep-lat/9610008 · doi:10.1016/S0550-3213(97)00591-9
Abstract
We discuss the regularization of chiral gauge theories on the lattice introducing only physical degrees of freedom. This is obtained by writing the Wilson term in a Majorana form, at the expense of the U(1) symmetry related to fermion number conservation. The idea of restoring chiral invariance in the continuum by introducing a properly chosen set of counterterms to be added to the tree level action is checked against one-loop perturbative calculations.
