Center Flux Correlation in SU(2) YangMills Theory
Abstract
By using the method of center projection, the center vortex part of the gauge field is isolated and its propagator is evaluated in the center Landau gauge, which minimizes the open 3dimensional Dirac volumes of nontrivial center links bounded by the closed 2dimensional center vortex surfaces. The center field propagator is found to dominate the gluon propagator (in the Landau gauge) in the low momentum regime and to give rise to a powerlaw correction {proportional_to}p{sup 2.9(1)} at high momentum. The screening mass of the center vortex field vanishes above the critical temperature of the deconfinement phase transition, which naturally explains the second order nature of this transition consistent with the vortex picture. Finally, the ghost propagator of the maximal center gauge is found to be infrared finite and, thus, shows that the coset fields play no role for confinement.

We construct and study a dimensionally reduced effective theory for hightemperature SU(2) YangMills theory that respects all the symmetries of the underlying theory. Our main motivation is to study whether the correct treatment of the center symmetry can help extend the applicability of the dimensional reduction procedure towards the confinement transition. After performing perturbative matching to the full theory at asymptotically high temperatures, we map the phase diagram of the effective theory using nonperturbative lattice simulations. We find that at lower temperature the theory undergoes a secondorder confining phase transition, in complete analogy with the full theory, which is amore »

Order parameter reconciling Abelian and center dominance in SU(2) YangMills theory
We analyze previously proposed order parameters for the confinementdeconfinement transition in lattice SU(2) YangMills theory, defined as vacuum expectation value (VEV) of monopole fields in Abelian projection gauges. We show that they exhibit some inconsistency in the treatment of small scales, due to a violation of Dirac quantization condition for fluxes. We propose a new order parameter avoiding this inconsistency. It can be interpreted as the VEV of the field of a regular monopole in any Abelian projection gauge, but it is independent of the choice of the Abelian projection. Furthermore, being constructed in terms of surfaces of center vortices,more » 
Center vortex model for the infrared sector of SU(3) YangMills theory: Baryonic potential
The baryonic potential in the framework of the SU(3) random vortex worldsurface model is evaluated for a variety of static color source geometries. For comparison, carefully taking into consideration the string tension anisotropy engendered by the hypercubic lattice description, also the {delta} and Y law predictions for the baryonic potential are given. Only the Y law predictions are consistent with the baryonic potentials measured. 
Center vortex model for the infrared sector of SU(3) YangMills theory: Vortex free energy
The vortex free energy is studied in the random vortex worldsurface model of the infrared sector of SU(3) YangMills theory. The free energy of a center vortex extending into two spatial directions, which is introduced into YangMills configurations when acting with the 't Hooft loop operator, is verified to furnish an order parameter for the deconfinement phase transition. It is shown to exhibit a weak discontinuity at the critical temperature, corresponding to the weak firstorder character of the transition. 
Center vortex model for the infrared sector of SU(4) YangMills theory: String tensions and deconfinement transition
A random vortex worldsurface model for the infrared sector of SU(4) YangMills theory is constructed, focusing on the confinement properties and the behavior at the deconfinement phase transition. Although the corresponding data from lattice YangMills theory can be reproduced, the model requires a more complex action and considerably more tuning than the SU(2) and SU(3) cases studied previously. Its predictive capabilities are accordingly reduced. This behavior has a definite physical origin, which is elucidated in detail in the present work. As the number of colors is raised in YangMills theory, the corresponding infrared effective vortex description cannot indefinitely continue tomore »
