   Common features of deconfining and chiral critical points in QCD and the three state Potts model in an external field

   F. Karsch🇩🇪 · Ch. Schmidt🇩🇪 · S. Stickan🇩🇪

   In the presented study we investigated the second order endpoints of the lines of first order phase transitions which emerge for the QCD in the heavy and light quark mass regime and for the three-dimensional three state Potts model with an external field. We located the endpoints with Binder cumulants and constructed the energy-like and ordering field like observables. The joint probability distributions of these scaling fields and the values of the Binder cumulant confirm that all three endpoints belong to the universality class of the 3-dimensional Ising model.

   Lattice Study of the High Density State of SU(2)-QCD

   S. Muroya (Tokuyama Women's Coll)🇯🇵 · A. Nakamura (IMC, Hiroshima University)🇯🇵 · C. Nonaka (IMC, Hiroshima University)🇯🇵

   We investigate high density state of SU(2) QCD by using Lattice QCD simulation with Wilson fermions. The ratio of fermion determinants is evaluated at each step of the Metropol is link update by Woodbury formula. At $\beta =0.7$, and $\kappa =0.150$, we calculate the baryon number density, the Polyakov lines, and the energy density of gluon sector with chemical potential $\mu$=0 to 0.8 on the $4^3\times 12$ lattice. Behavior of the meson propagators and diquark propagators with finite chemical potential are also investigated.
