Confinement and scaling of the vortex vacuum of SU(2) lattice gauge theory
Kurt Langfeld, Hugo Reinhardt, Oliver Tennert
Abstract
The magnetic vortices which arise in SU(2) lattice gauge theory in center projection are visualized for a given time slice. We establish that the number of vortices piercing a given 2-dimensional sheet is a renormalization group invariant and therefore physical quantity. We find that roughly 2 vortices pierce an area of 1 fm2.
