Dark Matter With Stückelberg Axions
Here, we review a class of models which generalize the traditional Peccei-Quinn (PQ) axion solution by a Stückelberg pseudoscalar. Such axion models represent a significant variant with respect to earlier scenarios, where axion fields were associated with global anomalies, because of the Stückelberg...
