### 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, Weff, in the coupling constants, gp of tree-level superpotential Wtree= gp Tr Φp/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 Weff.

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.
