The class of theories and the correlators we study are relevant for extending and testing mirror symmetry away from the (2,2) locus. More generally, these methods provide alpha'-exact results about certain superpotential couplings in compactifications of the heterotic string.20 pages; typos corrected; reference added; published versionHigh Energy Physics - Theorytext
