Measurement of the inelastic pp cross-section at a centre-of-mass energy of 13 TeV. J. High Energ. Phys. 2018, 100 (2018). https://doi.org/10.1007/JHEP06(2018)1001126-6708https://hdl.handle.net/10347/45026The cross-section for inelastic proton-proton collisions at a centre-of-mass energy of 13TeV is measured with the LHCb detector. The fiducial cross-section for inelastic interactions producing at least one prompt long-lived charged particle with momentum p > 2 GeV/c in the pseudorapidity range 2 < η < 5 is determined to be ϭ_acc=62,2 ± 0,2 ± 2,5mb. The first uncertainty is the intrinsic systematic uncertainty of the measurement, the second is due to the uncertainty on the integrated luminosity. The statistical uncertainty is negligible. Extrapolation to full phase space yields the total inelastic proton-proton cross-section ϭ_inel=75,4 ± 3,0 ± 4,5mb, where the first uncertainty is experimental and the second due to the extrapolation. An updated value of the inelastic cross-section at a centre-of-mass energy of 7TeV is also reported.engThis article is licensed under a Creative Commons Attribution 4.0 International License, which permits use, sharing, adaptation, distribution and reproduction in any medium or format, as long as you give appropriate credit to the original author(s) and the source, provide a link to the Creative Commons licence, and indicate if changes were made.Attribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/Global featuresHadron-Hadron scattering (experiments)Minimum biasjournal article10.1007/JHEP06(2018)1001029-8479open access
