3d mirror symmetry for theories with eight supercharges is understood in terms of Hanany-Witten brane setups and plays an important role in many areas of supersymmetric qft’s. The generalization to theories with four supercharges, in the non-Abelian case, has not been understood so far. In this talk, based on work in progress with Riccardo Comi and Sara Pasquetti, we focus on brane setups with NS and D5’ branes, proposing that the related quiver gauge theories involve ‘generalized bifundamentals’, that is strongly coupled qft’s which are ancestors of the well known T[SU(N)] theories. Our proposal leads to 3d mirror dualities that can be exactly proven, reducing them to known Seiberg-like dualities. This gives strong support to the proposal. The simplest example is the duality between adjoint SQCD with F flavors, and a generalized quiver with F-1 nodes and F-2 generalized bifundamentals.


Dr. Sergio Benvenuti is a researcher in INFN, Trieste, Italy. He tries to find exact results in Quantum Field Theories, mostly but not only for theories with low amount of supersymmetry in 2+1 and 3+1 dimensions.
