英文摘要 | Within the Dyson-Schwinger equation framework, a gluon propagator model incorporating a quark's feedback through operator product expansion is introduced to investigate the QCD phase diagram in the temperature-chemical-potential (T - mu) plane. Partial restoration of chiral symmetry at zero temperature and finite temperature are both studied, suggesting a first order phase transition point on the mu axis and a critical end point at (T-E,mu(E))/T-c = (0.85,1.11), where T-c is the pseudocritical temperature. In addition, we find the pseudocritical line can be well parametrized with the curvature parameter. and a consistent decrease in., with more of the gluon propagator distributed to the quark's feedback. |
