## Abstract

We determine the vacuum structure of script N = 2 supersymmetric QCD with fundamental quarks for gauge groups SO(n) and Sp(2n), extending prior results for SU(n). The solutions are all given in terms of families of hyperelliptic Riemann surfaces of genus equal to the rank of the gauge group. In the scale-invariant cases, the solutions all have exact S-dualities which act on the couplings by subgroups of PSL(2,ℤ) and on the masses by outer automorphisms of the flavor symmetry. They are shown to reproduce the complete pattern of symmetry breaking on the Coulomb branch and predict the correct weak-coupling monodromies. Simple breakings with squark vevs provide further consistency checks involving strong-coupling physics.
