Deconfining transition of SU(3) gauge theory on Nt=4 and 6 lattices

We report the results of a Monte Carlo study of finite-temperature pure SU(3) gauge theory performed on the parallel computer QCDPAX. The deconfining transition is studied on 122×24×4, 242×36×4, 243×6, and 362×48×6 lattices with 480 000–1 112 000 iterations. A clear two-phase structure is observed on spatially large (242×36×4 and 362×48×6) lattices and the gaps of physical quantities at the transition are calculated on these lattices. The latent heat thus obtained on the Nt=6 (362×48×6) lattice is much smaller than the one previously obtained
