Recent Results in the Center Vortex Model for the Infrared Sector of Yang-mills Theory
Diverse nonperturbative effects characterize strong interaction physics. Color charge is confined, chiral symmetry is spontaneously broken, and the axial U(1) part of the flavor symmetry exhibits an anomaly. Various model explanations for these phenomena have been advanced; to name but two widely accepted ones, the dual superconductor mechanism of confinement, and instanton models, which descri...
متن کاملCenter Vortex Model for the Infrared Sector of SU(3) Yang-Mills Theory
The vortex picture of the Yang-Mills vacuum, initially proposed as a possible mechanism of colour confinement, has recently attracted a renewed attention. This is mainly due to the advent of new gauge fixing techniques which permit the detection of center vortex structures directly within lattice Yang-Mills configurations. Numerical studies have revealed that the center projection vortices dete...
متن کاملVortex Model for the Infrared Sector of SU ( 3 ) Yang - Mills Theory – Vortex Free Energy
The vortex free energy is studied in the random vortex world-surface model of the in-frared sector of SU (3) Yang-Mills theory. The free energy of a center vortex extending into two spatial directions, which is introduced into Yang-Mills 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 ex...
متن کاملVortex Model for the Infrared Sector of SU ( 3 ) Yang - Mills Theory – Confinement and Deconfinement
The center vortex model for the infrared sector of Yang-Mills theory, previously studied for the SU (2) gauge group, is extended to SU (3). This model is based on the assumption that vortex world-surfaces can be viewed as random surfaces in Euclidean space-time. The confining properties are investigated, with a particular emphasis on the finite-temperature deconfining phase transition. The mode...
متن کاملCenter Vortex Model for SU(3) Yang-Mills Theory
The center vortex model for the infrared sector of SU(3) Yang-Mills theory is reviewed. After discussing the physical foundations underlying the model, some technical aspects of its realisation are discussed. The confining properties of the model are presented in some detail and compared to known results from full lattice Yang-Mills theory. Particular emphasis is put on the new phenomenon of vo...
