Exceptional Deconfinement in G ( 2 ) Gauge Theory
The Z Z(N) center symmetry plays an important role in the deconfine-ment phase transition of SU(N) Yang-Mills theory at finite temperature. The exceptional group G(2) is the smallest simply connected gauge group with a trivial center. Hence, there is no symmetry reason why the low-and high-temperature regimes in G(2) Yang-Mills theory should be separated by a phase transition. Still, we present...
متن کاملOn The Deconfinement Transition in SU(4) Lattice Gauge Theory
The deconfinement transition in SU(4) lattice gauge theory is investigated on N s × Nt lattices for Ns = 8–16 and Nt = 4–8 using a modified Wilson action which is expected to be free of any bulk transitions. The susceptibility χ |L| , where L is the order parameter for deconfinement, is found to increase linearly with spatial volume for Nt = 4, 5, and 6, indicating a first order deconfinement p...
متن کاملDeconfinement Transition in Large N Lattice Gauge Theory
We study analytically the phase diagram of the pure SU (N) lattice gauge theory at finite temperature, and we attempt to estimate the critical decon-finement temperature. We apply large N techniques to the Wilson and to the Heat Kernel action, and we study the resulting models both in the strong coupling and in the weak coupling limits. Using the Heat Kernel action, we establish an interesting ...
متن کاملMonopoles and deconfinement transition in SU(2) lattice gauge theory
We investigate SU(2) lattice gauge theory in four dimensions in the maximally abelian projection. Studying the effects on different lattice sizes we show that the deconfinement transition of the fields and the percolation transition of the monopole currents in the three space dimensions are precisely related. To arrive properly at this result the uses of a mathematically sound characterization ...
متن کاملThe Deconfinement Transition in Su (4) Lattice Gauge Theory
The nature of the phase transition(s) to QuarkGluon Plasma, which we hope to see in the experiments of RHIC and later of LHC, and the physics driving it, have always been of great interest. While the real world has presumably two very light (u,d) flavours of quarks and one somewhat heavier (s) flavour, both analytical and numerical methods in lattice QCD begin from the limiting cases of either ...
