Anomalous U(1)s masses in non-supersymmetric open string vacua

TL;DR

This paper extends the calculation of anomalous U(1) gauge boson masses to non-supersymmetric string models with D-branes, which is relevant for experimental implications of such theories.

Contribution

It provides the first detailed string-theoretic computation of anomalous U(1) masses in non-supersymmetric orientifold models, expanding previous supersymmetric results.

Findings

Extended the string calculation to non-supersymmetric cases

Derived explicit formulas for anomalous U(1) masses

Implications for experimental detection of string-inspired models

Abstract

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 relevant for experiment. In this paper, the string calculation of anomalous U(1) masses (hep-th/0204153) is extended to non-supersymmetric orientifolds.
