We present a preliminary study of the Globular Cluster RGB devoted to improve the available constraint for the axion-electron coupling. By means of multi-band IR photometry of the cluster M3 we obtain g a e / 1 0 − 13 < 2.57 g ae /10 −13 <2.57 (95% C.L.).

Abstract
We present a preliminary study of the Globular Cluster RGB devoted to improve the available constraint for the axion-electron coupling. By means of multi-band IR photometry of the cluster M3 we obtain g a e / 1 0 − 13 < 2.57 g ae /10 −13 <2.57 (95% C.L.).File in questo prodotto:
