Anomalous U(1)'s in type I string vacua
We perform a systematic string computation of the masses of anomalous U (1) gauge bosons in four-dimensional orientifold vacua, and we study their localization properties in the internal (compactified) space. We find that N = 1 supersymmetric sectors yield four- dimensional contributions, localized...
