Evidence for light-by-light scattering and searches for axion-like particles in ultraperipheral PbPb collisions at sNN=5.02TeV
A.M. Sirunyan, A. Tumasyan, W. Adam, F. Ambrogi et autres
Evidence for the light-by-light scattering process, γ γ → γ γ , in 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 an integrated luminosity of …
