Description
In earlier work, we used a gauge independent Abelian Decomposition to show that Abelian degrees of freedom where wholly responsible for the static quark postential. The Abelian decomposition contains a Maxwell part and Topological part, whose contribution to the string tension can be analysed theoretically and numerically, and arises because of the existence of a certain type of monopole. If we also fix the gauge in a certain way, we show that the Topological part can wholly account for the string tension. We show using numerical simulations in SU(2) Yang-Mills theory that the monopoles which can at least partially explain confinement are present in the QCD vacuum.
