Schwinger model chiral anomaly

WebA numerical investigation of the quenched Schwinger model on the lattice using the overlap Dirac operator points to a divergent chiral condensate. pacs: 11.15.Ha, 11.30Rd, 12.38Gc ... For the case of the chiral condensate ... WebWe study the overlap and the fixed point Dirac operators for massive fermions in the two-flavor lattice Schwinger model. The masses of the triplet (pion) and singlet (eta) bound states are determined down to small fermion masses and the mass dependence is compared with various continuum model approximations. Near the chiral limit, at very …
