Evidence for light-by-light scattering in heavy-ion collisions with the ATLAS detector at the LHC by ATLAS Collaboration Created 2026-10-24 Updated 2026-11-05
The ATLAS Collaboration reports the ATLAS evidence for light-by-light scattering in 2017 from ultra-peripheral collisions of lead ions. The paper states the event selection and background estimate; its abstract gives the candidate count and the fiducial scattering cross-section.
