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 de...
