Abstract
We study the phase structure of QCD at finite temperatures with two flavors of dynamical quarks on a lattice with the size Ns3 × Nt=163 × 4, using a renormalization group improved gauge action and a clover improved Wilson quark action. The simulations are made along the lines of constant physics determined in terms of m PS/m V at zero-temperature. We show preliminary results for the spatial string tension in the high temperature phase.
