Fermion Interactions in the Wilson Yukawa Approach for Lattice Chiral Gauge Theories | | Sinya Aoki

18 Jul 1992 | | Journal: | Prog.Theor.Phys. 88 (1992) 455-466 | | Subject: | hep-lat | | Abstract: | We consider fermion-gauge couplings in the Wilson-Yukawa approach for lattice chiral gauge theories. At the leading order of a fermionic hopping parameter expansion we find that the fermion-gauge coupling has a chiral and tree-like structure. We argue that this fermion-gauge coupling remains non-zero in the continuum limit taken in the Higgs phase. Possible fermion-scalar couplings in this approach are considered. We also evaluate the fermion interaction with an external gauge field in the slightly modified model and show that it has a chiral structure in general. | | Source: | arXiv, hep-lat/9207018 | | Services: | Forum | Review | PDF | Favorites | |
