We propose an efficient way to obtain a correct Veneziano-Yankielowicz type integration constant of the effective glueball superpotential Weff(S,g,Λ), even for massless theories. Applying our method, we show some = 1 theories do not have such an effective glueball superpotential, even though they have isolated vacua. In these cases, S = 0 typically. 

Gauge Theories and the Konishi Anomaly

We study chiral SU (N) supersymmetric gauge theories with matter in the antifundamental and antisymmetric representations. For SU (5) with two families, we show how to reproduce the

More on conformally sequestered supersymmetric breaking

This work extends models for conformal sequestering of dynamical supersymmetry breaking with decoupling vectorlike matter in several different ways to simplify concrete model building, in particular, rendering large gauge group and ad hoc global symmetry forsequestering unnecessary.

Chiral field theories, Konishi anomalies and matrix models

We study a chiral = 1, U(N) field theory in the context of the Dijkgraaf-Vafa correspondence. Our model contains one adjoint, one conjugate symmetric and one antisymmetric chiral multiplet, as well
