Equation of state and heavy-quark free energy at finite temperature and density in two flavor lattice QCD with Wilson quark action

Equation of state and heavy-quark free energy at finite temperature and density in two flavor lattice QCD with Wilson quark action

We study the equation of state at finite temperature and density in two-flavor QCD with the renormalization group improved gluon action and the clover-improved Wilson quark action on a ${16}^{3}\ifmmode\times\else\texttimes\fi{}4$ lattice. Along the lines of constant physics at ${m}_{\mathrm{PS}}/{m}_{\mathrm{V}}=0.65$ and 0.80, we compute the second and forth derivatives of the …
