摘要：The QCD thermodynamics on the lattice provides fundamental theoretical grounds to analyze the
various experimental data in relativistic heavy ion collisions. So far, most of the numerical simulations
on the lattice have been performed by using the staggered-type fermion actions. Therefore
it is important to carry out studies using different fermion formulations to test the uncertainties of
the lattice QCD results. For this purpose, we perform systematic simulations of two-flavor QCD
with an improved Wilson quark action to investigate the equation of state. We report the current
status of our project and show the preliminary results of the Taylor expansion coefficients of the
thermodynamic grand partition function in terms of chemical potential.
