A note on 4D heterotic string vacua, FI-terms and the swampland
We present a conjecture for the massless sector of perturbative 4D N=1 heterotic (0,2) string vacua, including U(1)n gauge symmetries, one of them possibly anomalous (like in standard heterotic compactifications). Mathematically it states that the positive hull generated by the charges of the massle...
