Upper bound on the Atiyah-Singer index from tadpole cancellation

Abstract We propose an upper bound on the Atiyah-Singer index in the effective action of string theory. For E 8 × E 8 ′ $$ {E}_8^{\prime } $$ and SO(32) heterotic string theories on smooth Calabi-Yau threefolds with line bundles, we find that the tadpole cancellation and supersymmetry conditions lea...
