Abstract: (Springer)
InSU(2) lattice gauge theory, we study deviations from ideal gas behaviour near the deconfinement point. On lattices of sizeNσ3×4,Nσ=8, 12, 18 and 26, we calculate the quantityΔ≡(ε−3P)/T4. It increases sharply just aboveTc, peaks atT/Tc=1.15 ±0.05 and then drops quickly. This form of behaviour is shown to be the consequence of a second order phase transition. Dynamically it could arise because just aboveTc, the low momentum states of the system are remnant massive modes rather than deconfined massless gluons.
