#ATLAS Experiment measures light scattering on light and constrains axion-like particles
“#ATLAS Experiment measures light scattering on light and constrains axion-like particles” Figure 1: Differential cross section of γγ→γγ production in lead–lead collisions at 5.02 TeV as a function of the invariant mass of the diphoton system and the cosine of the scattering angle in the photon-photon centre-of-mass frame, as measured by ATLAS. The measurements are…
