The ATLAS experiment at CERN has found evidence of a rare production process, with some reports suggesting it is related to the production of ZZy or three massive vector bosons. The experiment has also observed light-by-light scattering at high energy, which is a related phenomenon where particles are produced from collisions of light with light, including W-boson pair production. The findings appear to be part of a broader set of results from the ATLAS experiment, which has been analyzing data from high-energy collisions.
