Abstract: In recent years, rare-event searches targeting light dark matter particles or neutrinos via coherent elastic neutrino–nucleus scattering (CEvNS) have pushed their energy thresholds down to the eV scale. As thresholds have lowered, several experiments have begun to observe event rates exceeding their expected backgrounds. These low-energy EXCESSES typically rise steeply toward lower energies and significantly constrain experimental sensitivity. The EXCESS workshop series brings together experimentalists and theorists to share data, insights, and ideas, with the goal of identifying the origin of these excesses and developing mitigation strategies. This contribution summarizes the current status of EXCESS, based on a recently published review article.
