Measurement of the inelastic proton-proton cross section at √s=13 TeV
A measurement of the inelastic proton-proton cross section with the CMS detector at a center-of-mass energy of √ s = 13 TeV is presented. The analysis is based on events with energy deposits in the forward calorimeters, which cover pseudorapidities of −6.6 < η < −3.0 and +3.0 < η < +...

| Summary: | A measurement of the inelastic proton-proton cross section with the CMS
detector at a center-of-mass energy of √
s = 13 TeV is presented. The analysis is based on
events with energy deposits in the forward calorimeters, which cover pseudorapidities of
−6.6 < η < −3.0 and +3.0 < η < +5.2. An inelastic cross section of 68.6 ± 0.5(syst) ±
1.6(lumi) mb is obtained for events with MX > 4.1 GeV and/or MY > 13 GeV, where
MX and MY 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. |
