Coupling Constant in High Temperature QCD and Deconfinement Phase Transition

  • Finite temperature renormalization group equation is employed to investigate the effective coupling constant of QCD with respect to temperature.At high temperature,it is very small over the entire region of momentum,this leads to the property of deconfinement of QCD.

Abstract: Finite temperature renormalization group equation is employed to investigate the effective coupling constant of QCD with respect to temperature.At high temperature,it is very small over the entire region of momentum,this leads to the property of deconfinement of QCD.
