Evidence for light-by-light scattering and searches for axion-like particles in ultraperipheral PbPb collisions at √sNN=5.02 TeV
(2019) [Journal article]Evidence for the light-by-light scattering process,γγ→γγ, ultraperipheral PbPb collisions at a centre-of-mass energy per nucleon pair of 5.02 TeV is reported. The analysis is conducted using a data sample corresponding to ...
