Cross sections at CMS

This page aims to collect information about cross sections that are relevant for CMS. More on luminosity can be found here, and more on PDFs can be found here instead.

Get cross sections for particular CMS samples here:

• cross section database (XSDB) for CMS samples, e.g. for Drell-Yan
• summary table for 2016 samples
• summary table for 2017 samples, cross-check
• calculate for samples with GenXSecAnalyzer (CMSSW), see this example of useage

• 13 TeV summary (CMS TWiki)
• top quark pair production (NNLO+NNLL, CMS TWiki) with W boson branching fractions (PDG 2017), such that:

  TTTo2L2Nu:        BR(dilep)   = 10.6%       831.76 pb * (3*0.1086)^2        =  88.2877 pb
  TTToHadronic:     BR(had)     = 45.4%   =>  831.76 pb * (0.6741)^2          = 377.9607 pb
  TTToSemiLeptonic: BR(semilep) = 43.9%       831.76 pb * (2*3*0.1086*0.6741) = 365.3452 pb

• single top production (5FS NLO, CMS TWiki)

• LHC Higgs Cross Section Working Group (figures)
• LHC Standard Model Higgs production cross section values at 8 TeV and at 13 TeV which are published in the appendices of the Higgs Handbook Volume 4 (CERN Yellow Report)

• summary of measurements at CMS
• top pair production measurements at CMS: summary
