Non-Abelian Monopoles in the Higgs Phase

Understand

We use the moduli matrix approach to study the moduli space of 1/4 BPS kinks supported by vortices in the Higgs phase of N = 2 supersymmetric U(N) gauge theories when non-zero masses for the matter hypermultiplets are introduced.

• We focus on the case of degenerate masses.
• In these special cases vortices acquire new orientational degrees of freedom, and become "non-Abelian".
• Kinks acquire new degrees of freedom too, and we will refer to them as "non-Abelian".
