QCD WITH CHIRAL 4-FERMION INTERACTIONS (CHI-QCD)

摘要

Lattice QCD with staggered quarks is augmented by the addition of a chiral 4-fermion interaction. The Dirac operator is now non-singular at m(q) = 0, decreasing the computing requirements for light quark simulations by at least an order of magnitude. We present preliminary results from simulations at finite and sere temperatures for m(q) = 0, with and without gauge fields. [References: 9]
