Description
We used Borici-Creutz fermion to study discrete chiral symmetry breaking
at strong coupling in 2-dim Gross-Neveu model and mass spectra in 2-dim
field theories. Mixed action lattice QCD study with Borici-Creutz valence
quarks on staggered sea quarks is carried out. The counter terms are fixed
nonperturbatively to restore the broken symmetries. The effect of partial
quenching and unitarity violation is investigated.
