Abstract: (Elsevier)
After reviewing the euclidean formulation of the thermodynamics for quantum spin systems, we develop the corresponding formalism for SU( N ) gauge fields on the lattice. The results are then evaluated for the SU(2) system, using Monte Carlo simulation on lattices of (space × temperature) size 10 3 × 2,3,4,5. At high temperature, the system exhibits Stefan-Boltzmann behaviour, with three gluonic colour degrees of freedom. At T c ≈ 43 Λ L (215 MeV), the transition to “hadronic” behaviour occurs, signalled by a sharp peak in the specific heat. From the behaviour below the deconfinement transition ( T < T c ), we obtain m G ≈ 200 Λ L (1000 MeV) for the mass of the lowest gluonium state (glueball).
