Evidence for light-by-light scattering in ultraperipheral PbPb collisions at $\sqrt{s_{NN}}$ = 5.02 TeV
Evidence for light-by-light (LbL) scattering, γγ→γγ , in ultraperipheral PbPb collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV is reported. LbL scattering processes are selected in events with just two photons produced, with transverse energy ETγ>2GeV , pseudorapidity |ηγ|<2.4...
