QCD condensates with flavor SU(3) symmetry breaking

الأصل · EN

We investigate the effects of flavor SU(3)-symmetry breaking on the QCD condensates, based on the nonlocal effective chiral action from the instanton vacuum, focusing on the quark-gluon mixed one. We employ two different parameterizations for the dependence of the momentum-dependent dynamical quark mass on the strange current quark mass. We obtain the ratios of the mixed condensates:[<sσμνGμνs><u maμνGμνu>]¹/⁵=0.87. It turns out that the dimensional parameter m²₀=<q σμνGμνq>/ <qq> =1.60 1.92 GeV².
