### Papers on Superpotentials

Frank Ferrari has given a nice field-theoretic proof of (the simplest case of) the Dijkgraaf-Vafa proposal, using the methods of Intriligator-Leigh-Seiberg. The nifty thing is that the linearity of the effective superpotential, W_{eff}, in the coupling constants, g_{p} of tree-level superpotential W_{tree}= g_{p} Tr Φ^{p}/p (one of the main conclusions of ILS) is precisely equivalent to the statement of DV that only planar diagrams of the matrix integral contribute to W_{eff}.

Meanwhile, Becker and Constantin carry out some checks of Gukov’s conjecture about the form of the effective superpotential in String/M-theory compactifications with background fluxes.
