Photo-meson

This interaction is commonly referred to as photo-hadronic process.

The decay of charged mesons ultimately results in the production of neutrinos and electrons, with muons as an intermediate state.

The decay of neutral mesons produces high-energy gamma-rays.

Photo-meson production is one of the hadronic processes that can occur in cosmic ray sources as gamma-ray bursts and active galactic nuclei, and that can result in an observable multi-messenger signature.
