The 't Hooft-Polyakov Monopole in the Presence of an 't Hooft Operator

We present explicit BPS field configurations representing one nonabelian monopole with one minimal weight 't~Hooft operator insertion. We explore the $SO(3)$ and $SU(2)$ gauge groups.

In the case of $SU(2)$ gauge group the minimal 't~Hooft operator can be completely screened by the monopole. If the gauge group is $SO(3), $ however, such screening is impossible. In the latter case we observe a different effect of the gauge symmetry enhancement in the vicinity of the 't~Hooft operator.
