![]() | DeTar, Carleton | Continuum limit of lattice QCD with staggered quarks in the quenched approximation: a critical role for the chiral extrapolation | We calculate the light quark spectrum of lattice QCD in the quenched approximation using staggered quarks. We take the light quark mass, infinite volume, continuum limit. With nonlinear chiral extrapolations, we find that the nucleon to p mass ratio is mN/mp = 1.254 + 0.018 + 0.028, where the err... | Staggered quarks; Chiral extrapolations | 1998-10 |
