✦ Synopsis

We study the change of the meson and diquark propagators in a high density state of the two-color QCD with a Wilson fermion. Both Wilson gauge action and Iwasaki improved action are investigated. In order to explore the high density frontier of the phase space, we adopt an exact algorithm based on Woodbury formula which is quite robust but heavy. Lattice size is 43 x 8, a coupling is /3 = 0.70 and hopping parameter IC is 0.150 N 0.175 for the Iwasaki improved action. In any case of our simulation, the vector meson only reveals strange rising up with large chemical potential[l].

We report our recent numerical studies on two-color QCD with Wilson fermions. First the phase structure of the system in (n, p)-plane is analyzed by measuring Polyakov line, baryon number density, gluon energy density and Polyakov line susceptibility. Then meson and baryon (di-quark) propagators are
