Abstract:
Nonabelian magnetic monopoles of Goddard-Nuyts-Olive-Weinberg type have recently been shown to appear as the dominant infrared degrees of freedom in a class of softly broken N=2{\cal N}=2 supersymmetric gauge theories in which the gauge group GG is broken to various nonabelian subgroups HH by an adjoint Higgs VEV. When the low-energy gauge group HH is further broken completely by e.g. squark VEVs, the monopoles representing π2(G/H)\pi_2(G/H) are confined by the nonabelian vortices arising from the breaking of HH, discussed recently (hep-th/0307278). By considering the system with G=SU(N+1)G=SU(N+1), H = {SU(N) \times U(1) {\o}{\mathbb Z}_N}, as an example, we show that the total magnetic flux of the minimal monopole agrees precisely with the total magnetic flux flowing along the single minimal vortex. The possibility for such an analysis reflects the presence of free parameters in the theory - the bare quark mass mm and the adjoint mass μ\mu - such that for mμm \gg \mu the topologically nontrivial solutions of vortices and of unconfined monopoles exist at distinct energy scales.
