The onset of deconfinement inSU(2) lattice gauge theory

  • Published:

Abstract

InSU(2) lattice gauge theory, we study deviations from ideal gas behaviour near the deconfinement point. On lattices of sizeN 3σ ×4,N σ=8, 12, 18 and 26, we calculate the quantityΔ≡(ε−3P)/T 4. It increases sharply just aboveT c , peaks atT/T c =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 aboveT c , the low momentum states of the system are remnant massive modes rather than deconfined massless gluons.
