Description

We analyze 2+1 dimensional Yang-Mills theory on a spatial torus with twisted boundary conditions. It is conjectured that the physical quantities in the theory obey the so-called x-scaling, i.e. depend only on the variable x~NL/b and the magnetic flux, given by the parameters of the twist (L being the length of the spatial torus and b the inverse 't Hooft coupling). Using lattice approach and a broad range of values of N, we show numerical evidence supporting the x-scaling conjecture both in the non-zero electric flux sector and in the zero-flux (glueball) sector. Finally, generalization to 3+1 dimensions is discussed.
