Abstract: A bstract We show that 1 + 1 dimensional vacua of the (0 , 2) heterotic string have many properties in common with more recently studied physical systems. The free theory exhibits a symmetric product CFT structure. The single-string Hilbert space splits into sectors labeled by the string winding, w , that contain purely left-moving (for w > 0) and right-moving (for w < 0) excitations. These sectors exhibit infinite-dimensional left and right-moving symmetry algebras, respectively, with central extensions that depend on w . String interactions between left and right-movers appear to lead to a $$ T\overline{T} $$ T T ¯ deformation of the free theory.
