Abstract

Abstract : I generalize the deconstruction lattice formulation of Endres and Kaplan to two-dimensional super-QCD with eight supercharges, denoted by (4, 4), and bifundamental matter. I specialize to a particularly interesting (4, 4) gauge theory, with gauge groupU ( N c ) × U ( N f ), andU ( N f ) being weakly gauged. It describes the infrared limit of the D1/D5 brane system, which has been studied extensively as an example of the AdS3 /CFT2 correspondence. The construction here preserves two supercharges exactly and has a lattice structure quite similar to that which has previously appeared in the deconstruction approach, that is, site, link, and diagonal fields with both the Bose and Fermi statistics. I remark on possible applications of the lattice theory that would test the AdS3 /CFT2 correspondence, particularly one that would exploit the recent worldsheet instanton analysis of Chen and Tong.
