Physicists from the ATLAS experiment, one of the four major experiments at CERN’s Large Hadron Collider (LHC) in Switzerland, have found the first direct evidence of high energy light-by-light scattering, a quantum-mechanical process that is forbidden in the classical theory of electrodynamics. A candidate event of light-by-light scattering, a very rare process in which two photons interact and change direction, measured in the ATLAS detector. Image...
