Simulating the vacuum properties of QCD with dynamical quarks

High Energy Physics - Lattice 2009-10-30 v1

Abstract

The vacuum properties of lattice QCD with staggered quarks are investigated by an efficient simulation method. I present data for the quark condensate with flavor number Nf=0, 1, 2, 3, 4N_f=0, ~ 1, ~ 2, ~ 3, ~ 4 and many quark masses, including the vacuum energy in the chiral limit. Obvious sea quark effects are observed in some parameter space. I also describe a mechanism to understand this and a formula relating the chiral condensate and zero modes.
