dc.descriptionIn this article, I generalize the deconstruction lattice formulation of Endres and Kaplan [hep-lat/0604012] to two-dimensional super-QCD with eight supercharges, denoted (4,4), and bifundamental matter. I specialize to a particularly interesting (4,4) gauge theory, with gauge group U(N_c) \times U(N_f), and U(N_f) weakly gauged. It describes the infrared limit of the D1/D5 brane system, which has been studied extensively as an example of the AdS_3/CFT_2 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; i.e., site, link and diagonal fields with both Bose and Fermi statistics. I remark on possible applications of the lattice theory that would test the AdS_3/CFT_2 correspondence, particularly one that would exploit the recent worldsheet instanton analysis of Chen and Tong [hep-th/0604090].
