Measurement of the inelastic proton-proton cross section at $$ \sqrt{s}=13 $$ TeV

Abstract: 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 M X > 4.1 GeV and/or M Y > 13 GeV, where M X and M Y are the masses of the diffractive dissociation systems at negative and positive p… Show more

“…Shape uncertainties related to the pileup have been considered by varying the weights applied to simulation. This weight variation is obtained changing by 5% the total inelastic cross section used in the estimate of the pileup events in data [81]. The new values are then applied, event by event, to produce alternative collinear mass distributions used as shape uncertainties in the fit.…”

“…When the jet clustering algorithm is run, pileup can distort the reconstructed dijet system because of the contamination of tracks and calorimetric deposits. This uncertainty is evaluated by generating alternative distributions of the number of pileup interactions, corresponding to a 4.6% uncertainty in the total inelastic pp cross section at √ s = 13 TeV [67]. Limited number of simulated events.…”

“…Efficiency corrections for the selection of isolated leptons by the trigger and quality require- ments are evaluated with a tag-and-probe method. Uncertainties in correcting the distribution of PV interactions are accounted by varying the total inelastic cross section by 4.6% [60]. The corrections applied to the jet energy scale and resolution are varied within their given uncertainties and the migration between different categories is used to determine the effect.…”
