摘要：

Several physics aspects of the Seiberg-Witten solution of N = 2 supersymmetric Yang-Mills theory with SU(2) gauge group, supplemented with a small mass term for the ''matter'' fields which leads to an N = 1 theory with confinement, are discussed. We find in particular that in the massive (confining) theory the low energy physics has an exact CP symmetry, while in a generic vacuum in the massless theory CP invariance is broken spontaneously.
