The chiral symmetric transition phase in quantum chromodynamics

  • R. Acharya
  • P. Narayana Swamy


We develop the gauge technique to investigate the Dyson-Schwinger equation for the quark propagator in quantum chromodynamics. We retain the transverse vertex function and extend the theory to finite temperatures. We demonstrate thatTcTF: Chiral-symmetry restoration cannot take place before quark liberation. We conclude that chiral-symmetry restoration occurs at some critical temperatureTc as a result of the infrared properties of the transverse vertex function whose presence is responsible for the broken symmetric solution at zero temperature.
