The study uses $2.2$ nb$^{-1}$ of integrated luminosity collected in 2015 and 2018 at $\\sqrt{s_\\mathrm{NN}}=5.02$ TeV. Light-by-light scattering candidates are selected in events with two photons produced exclusively, each with transverse energy $E_{\\mathrm{T}}^{\\gamma} > 2.5$ GeV, pseudorapidity $|\\eta_{\\gamma}| < 2.37$, diphoton invariant mass $m_{\\gamma\\gamma} > 5$ 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. Cross sections above 2 to 70 nb are excluded at the 95% CL in that mass interval.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.95747.v1/t1","@type":"Dataset","description":"Measured differential fiducial cross sections of $\\gamma\\gamma \\rightarrow \\gamma\\gamma$ production in Pb+Pb collisions at $\\sqrt{s_{NN}}$ = 5.02 TeV for diphoton...","name":"Differential diphoton invariant mass"},{"@id":"https://doi.org/10.17182/hepdata.95747.v1/t2","@type":"Dataset","description":"Measured normalised differential fiducial cross sections of $\\gamma\\gamma \\rightarrow \\gamma\\gamma$ production in Pb+Pb collisions at $\\sqrt{s_{NN}}$ = 5.02 TeV for...","name":"Differential normalised diphoton invariant mass"},{"@id":"https://doi.org/10.17182/hepdata.95747.v1/t3","@type":"Dataset","description":"Measured differential fiducial cross sections of $\\gamma\\gamma \\rightarrow \\gamma\\gamma$ production in Pb+Pb collisions at $\\sqrt{s_{NN}}$ = 5.02 TeV for diphoton...","name":"Differential diphoton $|cos(\\theta*)|$"},{"@id":"https://doi.org/10.17182/hepdata.95747.v1/t4","@type":"Dataset","description":"Measured normalised differential fiducial cross sections of $\\gamma\\gamma \\rightarrow \\gamma\\gamma$ production in Pb+Pb collisions at $\\sqrt{s_{NN}}$ = 5.02 TeV for...","name":"Differential normalised diphoton $|cos(\\theta*)|$"},{"@id":"https://doi.org/10.17182/hepdata.95747.v1/t5","@type":"Dataset","description":"Measured normalised differential fiducial cross sections of $\\gamma\\gamma \\rightarrow \\gamma\\gamma$ production in Pb+Pb collisions at $\\sqrt{s_{NN}}$ = 5.02 TeV for...","name":"Differential average photon transverse momentum"},{"@id":"https://doi.org/10.17182/hepdata.95747.v1/t6","@type":"Dataset","description":"Measured normalised differential fiducial cross sections of $\\gamma\\gamma \\rightarrow \\gamma\\gamma$ production in Pb+Pb collisions at $\\sqrt{s_{NN}}$ = 5.02 TeV for...","name":"Differential normalised average photon transverse momentum"},{"@id":"https://doi.org/10.17182/hepdata.95747.v1/t7","@type":"Dataset","description":"Measured differential fiducial cross sections of $\\gamma\\gamma \\rightarrow \\gamma\\gamma$ production in Pb+Pb collisions at $\\sqrt{s_{NN}}$ = 5.02 TeV for diphoton...","name":"Differential diphoton rapidity"},{"@id":"https://doi.org/10.17182/hepdata.95747.v1/t8","@type":"Dataset","description":"Measured normalised differential fiducial cross sections of $\\gamma\\gamma \\rightarrow \\gamma\\gamma$ production in Pb+Pb collisions at $\\sqrt{s_{NN}}$ = 5.02 TeV for...","name":"Differential normalised diphoton rapidity"},{"@id":"https://doi.org/10.17182/hepdata.95747.v1/t9","@type":"Dataset","description":"The 95% CL upper limit on the ALP cross section $\\sigma_{\\gamma\\gamma\\rightarrow a \\rightarrow\\gamma\\gamma}$ for the $\\gamma\\gamma\\rightarrow a \\rightarrow \\gamma\\gamma$ process...","name":"The 95% CL upper limit on the ALP cross section"},{"@id":"https://doi.org/10.17182/hepdata.95747.v1/t10","@type":"Dataset","description":"The 95% CL upper limit on the ALP coupling $1/\\Lambda_{a}$ for the $\\gamma\\gamma\\rightarrow a \\rightarrow \\gamma\\gamma$ process as a function...","name":"The 95% CL upper limit on the ALP coupling $1/\\Lambda_{a}$"},{"@id":"https://doi.org/10.17182/hepdata.95747.v1/t11","@type":"Dataset","description":"Fiducial cross section for light-by-light scattering","name":"crossection"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1811464?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/95747"}],"inLanguage":"en","name":"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","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1811464?version=1","version":1}
