Anomalous Soft Photons: A Brief Overview
Abstract
These conference proceedings provide a compact experimental perspective on the soft-photon puzzle. The puzzle refers to the long-standing discrepancy between soft-photon data in hadronic reactions and predictions based on Low's soft-photon theorem. We summarize the theoretical baseline, representative measurements, and the main experimental challenges. For a detailed account of the experimental history and theory, we refer to the recent review article Phys. Rept., 1097:1, 2024.
