Evidence for light-by-light scattering and searches for axion-like particles in ultraperipheral PbPb collisions at √ s NN = 5.02 TeV
Evidence for the light-by-light scattering process, γγ→γγ, in ultraperipheral PbPb collisions at a centre-of-mass energy per nucleon pair of 5.02TeV is reported. The analysis is conducted using a data sample corresponding to an integrated luminosity of 390μb−1 recorded by the CMS experiment at the L...
