On N=2 MQCD
T. Nakatsu
Abstract
We review M-theory description of 4d N=2 SQCD. Configurations of M-theory fivebranes relevant to describe the moduli spaces of the Coulomb and Higgs branches are studied using the Taub-NUT geometry. Minimal area membranes related with the BPS states of N=2 SQCD are given explicitly. They almost saturate the BPS bounds. The deviation from the bounds is due to their boundary condition constrained by the fivebrane. The electric-magnetic duality at the baryonic branch root is also examined from the M-theory viewpoint. In this course, novel concepts such as creation of brane and exchange of branes in Type II theory are explained in the framework of M-theory.
