Measurement of light-by-light scattering and search for axion-like particles with 2.2 nb−1 of Pb+Pb data with the ATLAS detector
Original language description
This paper describes a measurement of light-by-light scattering based on Pb+Pb collision data recorded by the ATLAS experiment during Run 2 of the LHC. The study uses 2.2 nb−1^{−1}−1 of integrated luminosity collected in 2015 and 2018 at sNN sqrt{s_{mathrm{NN}}} sNN = 5.02 TeV. Light-by-light scattering candidates are selected in events with two photons produced exclusively, each with transverse energy ETγ {E}_{mathrm{T}}^{gamma } ETγ> 2.5 GeV, pseudorapidity |ηγ_{γ}γ| < 2.37, diphoton invariant mass mγγ_{γγ}γγ> 5 GeV, and with small diphoton transverse momentum and diphoton acoplanarity. The integrated and differential fiducial cross sections are measured and compared with theoretical predictions. The diphoton invariant mass distribution is used to set limits on the production of axion-like particles. This result provides the most stringent limits to date on axion-like particle production for masses in the range 6–100 GeV.n
