| 内容記述 | We study the equation of state in two-flavor QCD at finite temperature and density. Simulations are made with the RG-improved gluon action and the clover-improved Wilson quark action. Along the lines of constant physics for mPS/mV = 0.65 and 0.80, we compute the derivatives of the quark determinant with respect to the quark chemical potential μq up to the fourth order at μq = 0. We adopt several improvement techniques in the evaluation. We study thermodynamic quantities and quark number susceptibilities at finite μq using these derivatives. We find enhancement of the quark number susceptibility at finite μq, in accordance with previous observations using staggered-type quarks. This suggests the existence of a nearby critical point. | |||||
