Center Vortices and K-strings
The vortex contribution to the k-string tensions is computed for SU(N) gauge theories. We deduce the surface densities needed to reproduce the sine scaling and the Casimir scaling formulae, recently obtained from numerical simulations on the lattice. We find that such densities need to grow linearly in N , which in turn suggests that the vortex scenario can hardly reproduce the physics of confi...
متن کاملCenter Vortices
We review recent progress in understanding the center-vortex picture of con nement for SU(N). A notable development is the spectacular con rmation on the lattice of center-vortex predictions for topological con nement and the area law in the fundamental-representation Wilson loop. Recent theoretical progress includes: large-N scaling, the heavy-quark potential for SU(3) baryons, the breakable \...
متن کاملTopology of Center Vortices
The topology of center vortices is studied. For this purpose it is sufficient to consider mathematically idealised vortices, defined in a gauge invariant way as closed (infinitely thin) flux surfaces (in D=4 dimensions) which contribute the nth power of a non-trivial center element to Wilson loops when they are n-foldly linked to the latter. In ordinary 3-space generic center vortices represent...
متن کاملConfinement and Fat-center-vortices Model
In this paper I review shortly potentials obtained for SU(2), SU(3) and SU(4) static sources from fat-center-vortices model. Results confirm the confinement of quarks in all three gauge groups. Proportionality of string tensions with flux tube counting is better than Casimir scaling especially for SU(4).
متن کاملTopological charge of Center Vortices
Center vortices provide an appealing picture of confinement [1]. When center vortices are removed from the Yang-Mills ensemble, the string tension [2] and the quark condensate [3] are lost. Therefore one should expect that center vortices can also explain spontaneous breaking of chiral symmetry. The mechanism of spontaneous breaking of chiral symmetry seems to be tied to the topological propert...
