Fayet–Iliopoulos D-term in non-supersymmetric heterotic string orbifolds
Abstract The Fayet–Iliopoulos D-term is a common feature in $${\mathcal {N}}=1$$ N = 1 string vacua that contain an anomalous U(1) gauge symmetry, and arises from a one-loop diagram in string perturbation theory. The same diagram is generated in string vacua in which supersymmetry is broken directly...
