Anomalous soft photon production can be understood as photon emission during hadronisation

Year: 2026

Type: preprint

Abstract: Several experiments reported measurements of soft photons in hadronic collisions far above the predictions from QED. This work investigates possible production during the hadronisation process. It is shown that the assumption of isotropic emission of photons during the hadronisation process leads to a consistent description of the experimental data.
