Abstract
The deconfining transitions of SU(N) lattice gauge theories, both with and without quarks, are studied using strong coupling techniques combined with a mean field analysis. In the pure gauge sector our analysis suggests first-order transitions for N ⩾ 3 and a second-order transition only for N = 2. Quarks are incorporated via an effective external field h related to the Wilson hopping parameter. For N = 2 the transition disappears for arbitrarily small h, whereas for finite N ⩾ 3 it disappears above non-zero critical field hc. hc approaches zero as N → ∞ even though the pure gauge sector transition remains first order. Our results for hc in t…(more)
