Abstract:
The Coulomb branch of N=2N=2 supersymmetric gauge theories in four dimensions is described in general by an integrable Hamiltonian system in the holomorphic sense. A natural construction of such systems comes from two-dimensional gauge theory and spectral curves. Starting from this point of view, we propose an integrable system relevant to the N=2N=2 SU(n)SU(n) gauge theory with a hypermultiplet in the adjoint representation, and offer much evidence that it is correct. The model has an SL(2,Z)SL(2,{\bf Z}) SS-duality group (with the central element 1-1 of SL(2,Z)SL(2,{\bf Z}) acting as charge conjugation); SL(2,Z)SL(2,{\bf Z}) permutes the Higgs, confining, and oblique confining phases in the expected fashion. We also study more exotic phases.
