Heterotic instanton superpotentials from complete intersection Calabi-Yau manifolds

Abstract:

We study Pfaffians that appear in non-perturbative superpotential terms arising from worldsheet instantons in heterotic theories. A result by Beasley and Witten shows that these instanton contributions cancel among curves within a given homology class for Calabi-Yau manifolds that can be described as hypersurfaces or complete intersections in projective or toric ambient spaces. We provide a prescription that identifies all ℙ 1 curves in certain homology classes of complete intersection Calabi...
