This Letter presents a measurement of the inelastic proton-proton cross section using 60 μb−1 of pp collisions at a center-of-mass energy s√ of 13 TeV with the ATLAS detector at the LHC. Inelastic interactions are selected using rings of plastic scintillators in the forward region (2.0713 GeV. The measured cross section is compared with a range of theoretical predictions. When extrapolated to the full phase space, a cross-section of 78.1±2.9 mb is measured, consistent with the inelastic cross section increasing with center-of-mass energy.
