Description

We provide an overview of the soft-photon puzzle, i.e., of the long-standing discrepancy between experimental data and predictions based on Low’s soft-photon theorem, also referred to as “anomalous” soft photon production, and we briefly review the current theoretical understanding of soft radiation and soft theorems. We discuss how both topics can be addressed with the planned ALICE 3 detector at the LHC.
