Gravitational couplings in N $$ \mathcal{N} $$ = 2 heterotic compactifications with Wilson lines
Abstract In this paper we compute the gravitational couplings of the heterotic string compactified on (K3 × T 2)/ℤ N and E 8 × E 8 and predict the Gopakumar Vafa invariants of the dual Calabi Yau manifold in presence of Wilson lines. Here ℤ N acts as an automorphism on K3 associated with the conjuga...
