An estimate of the chiral condensate from unquenched lattice QCD
Abstract
Using the parameters in the chiral Lagrangian obtained by MILC from their unquenched lattice QCD calculations with 2+1 flavours of sea quarks, I estimate <psibar psi> (2 GeV)/nf = -(259 27 MeV)**3 in the MSbar scheme. I compare this value to other determinations.
