Vortex Model for the Infrared Sector of SU ( 3 ) Yang - Mills Theory – Vortex Free Energy
نویسندگان
چکیده
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 exhibit a weak discontinuity at the critical temperature, corresponding to the weak first order character of the transition.

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 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 کاملString tensions and deconfinement transition in the SU(4) center vortex model
A center vortex model for the infrared sector of SU(4) Yang-Mills theory is constructed such as to reproduce both the ratio between the zero-temperature quark and diquark string tensions known from lattice Yang-Mills theory, as well as the properties of the deconfinement transition. On this basis, the temperature dependence of the spatial quark and diquark string tensions is predicted. Though s...

A model for the infrared sector of SU(2) Yang-Mills theory, based on magnetic vortices represented by (closed) random surfaces, is presented. The model quantitatively describes both confinement (including the finite-temperature transition to a deconfined phase) and the topological susceptibility of the Yang-Mills ensemble. A first (quenched) study of the spectrum of the Dirac operator furthermo...
