M-THEORY AND DYNAMICS OF SUPERSYMMETRIC GAUGE THEORIES

Abstract

The study of brane configuations has played a rich role in nonperturbative dynamics of SUSY gauge theories. We consider brane configurations in M-theory describing N = 1 supersymmetric gauge theories and using the parametric representation of the brane configurations, we can calculate the superpotentials for various cases including multiple gauge groups or fermions. For SU(n) N = 1 SQCD with N_f fermion case (N_f < N_c), we find that the superpotential from M-theory and the gauge theory agree precisely.
