Description

Following our discovery of a significant signal in photon-photon data near 38 MeV, it was declared by the responsible Collaboration to be due to a detector artefact. We will show that the latter claim is not substantiated by the data simulation produced by the Collaboration and, moreover, present further experimental and theoretical results which support the existence of a boson lighter than the pion.
