Type I superconductivity upon monopole condensation in Seiberg-Witten theory

We study the confinement scenario in N = 2 supersymmetric SU(2) gauge theor y near the monopole point upon breaking of N = 2 supersymmetry by the adjoi nt matter mass term. We confirm claims made previously that the Abrikosov-N ielsen-Olesen string near the monopole point fails to be a BPS state once n ext-to-leading corrections in the adjoint mass parameter taken into account . Our results shows that type I superconductivity arises upon monopole cond ensation. This conclusion allows us to make qualitative predictions on the structure of the hadron. mass spectrum near the monopole point. (C) 2001 Pu blished by Elsevier Science B.V.
