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

Abstract

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 $β=0.7$, and $κ= 0.150$, we calculate the baryon number density, the Polyakov lines, and the energy density of gluon sector with chemical potential $μ$=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.
