Title: Universality class and the chiral phase transition in QCD †Speaker: Kohei Fujikura †Landau-Ginzburg-Wilson (LGW) theory, based on the argument of universality, is a powerful effective theory that describes the dynamics of various phase transitions [1,2]. Pisarski and Wilczek constructed the LGW Hamiltonian of the QCD chiral phase transition and analyze the dynamics of the phase transition at one-loop order. They concluded that the phase transition is of (fluctuation-induced) first order for two or more massless quarks when U(1)_A is fully recovered during the phase transition [3]. In this talk, I will review the argument of universality and its application to QCD (chiral) phase transition. References: |
