Towards Weyl fermions on the lattice without artefacts
arXiv:0710.5346 · doi:10.1088/1126-6708/2008/02/079
Abstract
In spite of the breakthrough in non-perturbative chiral gauge theories during the last decade, the present formulation has stubborn artefacts. Independently of the fermion representation one is confronted with unwanted CP violation and infinitely many undetermined weight factors. Renormalization group identifies the culprit. We demonstrate the procedure on Weyl fermions in a real representation.
