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.

Dark matter as ultralight axion-like particle in E6 × U(1) GUT with QCD axion
Abstract Axion-like fields are naturally generated by a mechanism of anomaly cancellation of one or more anomalous gauge abelian symmetries at the Planck scale, emerging as duals of a two-form from
Dark Matter With Stückelberg Axions
We review a class of models which generalize the traditional Peccei-Quinn (PQ) axion solution by a Stuckelberg pseudoscalar. Such axion models represent a significant variant with respect to earlier
