 Title:  Aspects of heterotic AdS/CFT

 Abstract:  I discuss the AdS_3/CFT_2 duality of a heterotic three-charge model with (0,4) target space supersymmetry. The corresponding worldsheet theory for heterotic strings was previously constructed by Kutasov, Larsen and Leigh. I propose that the dual conformal field theory is given by a two-dimensional (0,4) sigma model arising on the Higgs branch of an orbifolded ADHM model. As a non-trivial consistency check of the correspondence, I show that the left- and right-moving central charges of the infrared conformal field theory agree with those predicted by the worldsheet model.
