We investigate 't Hooft-Mandelstam monopoles in QCD in the presence of a single classical instanton con guration. The solution to the Maximal Abelian projection is found to be a circular monopole trajectory with radius R centered on the instanton. At zero loop radius, there is a marginally stable (or at) direction for loop formation to O(RlogR). We argue that loops will form, in the semi-classical limit, due to small perturbations such as the dipole interaction between instanton anti-instanton… CONTINUE READING
