Generalized Yukawa couplings and Matrix Models
Iosif Bena, Sebastian de Haro, Radu Roiban
In this note we investigate U(N) gauge theories with matter in the fundamental and adjoint representations of the gauge group, interacting via generalized Yukawa terms of the form…
Baryons, Boundaries and Matrix Models
Iosif Bena, Radu Roiban, Radu Tatar
A natural extension of the Dijkgraaf-Vafa proposal is to include fields in the fundamental representation of the gauge group. In this paper we use field theory techniques to analyz…
Exact superpotentials in N=1 theories with flavor and their matrix model formulation
Iosif Bena, Radu Roiban
In this note we investigate the effective superpotential of an N=1 SU(N_c) gauge theory with one adjoint chiral multiplet and N_f fundamental chiral multiplets. We propose a matrix…
Supergravity pp-wave solutions with 28 and 24 supercharges
Iosif Bena, Radu Roiban
We conduct an exhaustive search for solutions of IIA and IIB supergravity with augmented supersymmetry. We find a two-parameter family of IIB solutions preserving 28 supercharges,…
