Axion-like particles and e-ASTROGAM

Abstract

e-ASTROGAM is a space mission with unprecedented sensitivity to photons in the MeV range, proposed within the ESA M5 call. In this note we describe some measurements sensitive to axion-like particles, for which performance in the MeV/GeV range is of primary importance, and e-ASTROGAM could be the key for discovery. Keywords: Axions. ALPs. Dark-matter candidates. Gamma-ray astrophysics.
