Anomalous U(1)s masses in non-supersymmetric open string vacua
P. Anastasopoulos
Anomalous U(1)s are omnipresent in realizations of the Standard Model using D-branes. Such models are typically non-supersymmetric, and the anomalous U(1) masses are potentially re…

4D Anomalous U(1)'s, their masses and their relation to 6D anomalies
P. Anastasopoulos
In some four-dimensional orientifolds, U(1) gauge fields that are free of four-dimensional anomalies can still be massive. It is shown that this is due to mass-generating six-dimen…
