Abstract

A measurement of the inelastic proton-proton cross section with the CMS detector at a center-of-mass energy of 13 TeV is presented. The analysis is based on events with energy deposits in the forward calorimeters, which cover pseudorapidities of -6.6 -3.0 and +3.0 +5.2. An inelastic cross section of 68.6 0.5 (syst) 1.6 (lumi) mb is obtained for events with 4.1 GeV and/or 13 GeV, where and are the masses of the diffractive dissociation systems at negative and positive pseudorapidities, respectively. The results are compared with those from other experiments as well as to predictions from high-energy hadron-hadron interaction models.

Replaced with the published version. Added the journal reference and the DOI. All the figures and tables can be found at http://cms-results.web.cern.ch/cms-results/public-results/publications/FSQ-15-005 (CMS Public Pages)
