28 Nov 1992 | Journal: | Nucl.Phys. B407 (1993) 373-386 | Subject: | hep-lat | Abstract: | Using the Zaragoza proposal for lattice chiral gauge fermions, the S, U and Delta
ho parameters have been calculated at one loop. It is shown that the continuum values for these quantities can be reproduced without requiring explicit fine tuning of counterterms. Furthermore, fermion fields doubling is not necessary. To the best of our knowledge, the Zaragoza proposal is the only scheme which has these properties. A necessary (although not sufficient) symmetry is found to support the calculations. Previous results for some of these parameters in other lattice chiral regularizations are revisited in the light of this symmetry. | Source: | arXiv, hep-lat/9211065 | Services: | Forum | Review | PDF | Favorites |
