We give a simple description of the classical moduli space of vacua for supersymmetric gauge theories with or without a superpotential. The key ingredient in our analysis is the observation that theâ€¦ (More)

We consider supersymmetric Sp(2N) gauge theories with F matter elds in the de ning representation, one matter eld in the adjoint representation, and no superpotential. We construct a sequence of dualâ€¦ (More)

We show that the leading SU(3)-breaking corrections to the âˆ†S = 1 f1 vector form factors of hyperons are O(ms) and O(m 3/2 s ), and are expected to be âˆ¼ 20â€“30% by dimensional analysis. This isâ€¦ (More)

We consider flavor breaking in the the octet and decuplet baryon masses at second order in large-N chiral perturbation theory, where N is the number of QCD colors. We assume that 1/N âˆ¼ 1/NF âˆ¼ ms/Î› â‰«â€¦ (More)

We use the observed SU(3) breaking in the mass spectrum of mesons containing a single heavy quark to place restrictions on the light quark current masses. A crucial ingredient in this analysis is ourâ€¦ (More)
