The ATLAS collaboration E-mail: email@example.com Erratum to: JHEP02(2020)042 ArXiv ePrint: 1911.00453 Figure 5b of the paper  contained a misinterpretation in the comparison between the reported new ATLAS measurement of the process pp ! Xp and previously published CMS data . The ATLAS measurement corresponds to cases where either proton dissociates. In the comparison, the CMS measurement was assumed to be defined similarly, whereas in fact it includes the dissociation of only one of the protons. On further investigation, the comparison between the ATLAS and CMS measurements is far from straightforward. The double dissociation (pp → XY ) contribution in the CMS data is not well constrained and indications from the CMS analysis suggest it may be significantly larger than was thought originally. Fuerthermore, the potentially sizeable central diffraction (pp → pXp) contribution was subtracted in the ATLAS measurement, but included by CMS. There is also a small effect associated with the different centre of mass energies (7 TeV for CMS and 8 TeV for ATLAS). In view of these complications, the figure has now been withdrawn from the publication .
