摘要：

We report the first measurements of sixth order non-linear quark number susceptibilities in continuum QCD. This extends our earlier computation of the continuum limit [1] of non-linear quark number susceptibilities and the pressure in QCD for m/T-c, = 0.1. For T/T-c greater than or equal to 1.5, no phase transitions are observable for mu < 30T. Systematics of off-diagonal susceptibilities are reported. The equation of state in the high temperature phase of the QCD plasma is constructed.
