Constraining MeV-scale axion-like particles with Fermi-LAT observations of SN 2023ixf

Abstract

The Fermi-LAT observations of SN 2023ixf, a Type II supernova in the nearby Pinwheel Galaxy, Messier 101 (M101), presents us with an excellent opportunity to constrain MeV-scale Axion-Like Particles (ALPs). By examining the photon decay signature from heavy ALPs that could be produced in the explosion, we improve the existing constraints on the ALP-photon coupling by up to a factor of $ \sim 2 $ for masses $ m_a \lesssim 3 $ MeV, with the exact value depending mostly on plasma properties of the collapsing core. This study demonstrates the relevance of core-collapse supernovae, also beyond the Magellanic Clouds, as probes of fundamental physics.
