't Hooft tensor for generic gauge group
arXiv:0809.2154 · doi:10.1016/j.nuclphysbps.2008.12.052
Abstract
We study monopoles in gauge theories with generic gauge group. Magnetic charges are in one-to-one correspondence with the second homotopy classes at spatial infinity ($Î _2$), which are therefore identified by the 't Hooft tensor. We determine the 't Hooft tensor in the general case. These issues are relevant to the understanding of Color Confinement.
