M-THEORY AND THE INTEGRATING IN METHOD WITH AN ANTISYMMETRIC TENSOR -ART. NO. 066002

Recently, a nonhyperelliptic curve describing the Coulomb branch of N= 2 SUSY SU(N-c) Yang-Mills theory with antisymmetric tensor matter was proposed using the configuration of a single M theory five-brane. We s tudy the singular surface in the moduli space of the curve to compare it with results from the ''integrating in'' method in field theory. In order to achieve consistency, we find it necessary to take into accou nt an additional superpotential W-Delta which has been neglected so fa r. The explicit form of W-Delta is worked out.
