Features in the globular cluster luminosity functions (LF) of the post-main sequence stellar evolution can be used to investigate modifications of standard stellar models and to look for new physics fingerprints, like axions or hidden photons. Here, we investigate the possible effects of hidden photons during the red giant branch (RGB) phase. In a follow-up analysis, these results will be applied to discuss signatures and observational effects in the globular cluster LF.

Abstract
Features in the globular cluster luminosity functions (LF) of the post-main sequence stellar evolution can be used to investigate modifications of standard stellar models and to look for new physics fingerprints, like axions or hidden photons. Here, we investigate the possible effects of hidden photons during the red giant branch (RGB) phase. In a follow-up analysis, these results will be applied to discuss signatures and observational effects in the globular cluster LF.File in questo prodotto:
