Progress in vacuum susceptibilities and their applications to the chiral phase transition of QCD

ZF Cui, FY Hou, YM Shi, YL Wang, HS Zong - Annals of Physics, 2015 - Elsevier
The QCD vacuum condensates and various vacuum susceptibilities are all important
parameters which characterize the nonperturbative properties of the QCD vacuum. In the …

Light pseudoscalar mesons in a nonlocal chiral quark model
