Proton-proton collision data recorded in 2017 at a centre-of-mass energy of $\\sqrt{s}=$13 TeV were analysed, corresponding to an integrated luminosity of 14.6 fb$^{-1}$. A total of 441 candidate signal events were selected. A search was made for a narrow resonance in the diphoton mass distribution, corresponding to an axion-like particle (ALP) with mass in the range 150-1600 GeV. No excess is observed above a smooth background. Upper limits on the production cross section of a narrow resonance are set as a function of the mass, and are interpreted as upper limits on the ALP production coupling constant, assuming 100% decay branching ratio into a photon pair. The inferred upper limit on the coupling constant is in the range 0.04-0.09 TeV$^{\u22121}$ at 95% confidence level.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.140956.v1/t1","@type":"Dataset","description":"Signal selection efficiency as a function of ALP mass $m_{\\textrm{X}}$ for the exclusive (EL), single-dissociative (SD), and double-dissociative (DD) processes....","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.140956.v1/t2","@type":"Dataset","description":"The diphoton mass distribution of the mixed-data sample (black points).","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.140956.v1/t3","@type":"Dataset","description":"The $(\\xi_{\\gamma\\gamma}^{+},\\xi_{\\gamma\\gamma}^{-})$ distribution of the selected data candidates after the full event selection in $m_{\\gamma\\gamma}$ in [150,1600] GeV with $m_{\\gamma\\gamma}$...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.140956.v1/t4","@type":"Dataset","description":"Background-only fit to the observed numbers of events (black points) as a function of the diphoton invariant mass $m_{\\gamma\\gamma}$.","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.140956.v1/t5","@type":"Dataset","description":"Expected and observed 95% CL upper limits on the signal fiducial cross section $\\sigma_{\\textrm{fid}}$, assuming 100% branching ratio for ALP...","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.140956.v1/t6","@type":"Dataset","description":"Expected and observed 95% CL upper limits on the the ALP coupling constant, assuming 100% branching ratio for ALP decay...","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.140956.v1/t7","@type":"Dataset","description":"Fiducial region acceptance of signal events for coupling constant f$^{-1}=0.05$ TeV$^{-1}$.
