Contribution

It provides an overview of supersymmetric constructions of axion-like particles and summarizes recent experimental efforts to detect them at the LHC.

Findings

LHC studies have begun to explore production rates of gauged axions.

Theoretical frameworks connect axions to anomaly cancellation mechanisms.

Abstract

Axion-like particles are an important part of the spectrum of anomalous gauge theories involving modified mechanisms of cancellation of the gauge anomalies. Among these are intersecting brane models, which are characterized by the presence of one physical axion. We overview a recent study of their supersymmetric construction and some LHC studies of the productions rates for a gauged axion.
