✦ Synopsis

We report lattice computations in SU(N c ) pure gauge theory, where N c is increased beyond the physical value of 3. We demonstrate two-loop scaling of T c , thus obtaining the variation of T c /ΛMS with N c , and fixing the temperature scale. We study the equation of state of the gluoN c plasma, the conformal anomaly, and the approach to the weak coupling theory. We find that the weak-coupling prediction is always closer to the lattice data than the conformal field theory is.
