BPS spectra and non-perturbative gravitational couplings in N=2,4 supersymmetric string theories
We study the BPS spectrum in D=4, N=4 heterotic string compactifications, with some emphasis on intermediate N=4 BPS states. These intermediate states, which can become short in N=2 compactifications, are crucial for establishing an S-T exchange symmetry in N=2 compactifications. We discuss the impl...
