Title: | Measurement of the inclusive isolated-photon cross section in pp collisions at √s = 13 TeV using 36 fb−1 of ATLAS data | Authors: | Fiolhais, M. C. N. Veloso, F. Wolters, H. ATLAS Collaboration |
Keywords: | Hadron-Hadron scattering (experiments); Photon production; QCD | Issue Date: | 2019 | Publisher: | Springer Nature | Serial title, monograph or event: | Journal of High Energy Physics | Volume: | 2019 | Issue: | 10 | Abstract: | The differential cross section for isolated-photon production in pp collisions is measured at a centre-of-mass energy of 13TeV with the ATLAS detector at the LHC using an integrated luminosity of 36:1 fb1. The di erential cross section is presented as a function of the photon transverse energy in di erent regions of photon pseudorapidity. The di erential cross section as a function of the absolute value of the photon pseudorapidity is also presented in di erent regions of photon transverse energy. Next-to-leading-order QCD calculations from Jetphox and Sherpa as well as next-to-next-to-leading-order QCD calculations from Nnlojet are compared with the measurement, using several parameterisations of the proton parton distribution functions. The predictions provide a good description of the data within the experimental and theoretical uncertainties. | URI: | https://hdl.handle.net/10316/107119 | DOI: | 10.1007/JHEP10(2019)203 | Rights: | openAccess |
