The systematic uncertainties for the nominal muon-channel cross-section measurement. Some sources of uncertainty have both correlated and uncorrelated components. Correlated uncertainties arise from the uncertainty in the electroweak background contributions delta(e.w.)_cor, from corrections to the Monte Carlo modelling of the Z/gamma* pT spectra, and from the reconstruction, trigger and isolation efficiency corrections, given by delta(reco)_cor, delta(trig)_cor and delta(iso)_cor respectively. The uncertainty on the multijet and electroweak background cross sections, given by delta(multijet and delta(e.w.), respectively and muon momentum scale uncertainty, delta(pT_scale) are also correlated. Uncorrelated uncertainties are due to corrections for the trigger and isolation efficiencies, given by delta(trig)_unc and delta(iso)_unc respectively. The uncertainty from the muon resolution correction, delta(res), from the size of the signal Monte Carlo sample, delta(MC), and the uncertaintities due to corrections for the reconstruction, delta(reco)_unc, are also uncorrelated. The luminosity uncertainty 1.8% is not included.

As the uncertainties on the combined result no longer originate from individual error sources they are numbered 1-13. Also shown is the correction factor used to derive the dressed cross section (D), and the NNLO extrapolation factor (A) used to derive the cross section for the full phase space, along with the uncertainties associated to variations in scale choice delta(A)_scale, and PDF uncertainty delta(A)_pdf_alpha_s.

The systematic uncertainties for the extended muon channel cross-section measurement in each invariant mass bin. Correlated uncertainties come from the reconstruction, trigger and isolation efficiency corrections, given by delta(reco), delta(trig) and delta(iso) respectively. The uncertainty on the multijet background cross section, delta(multijet) and the uncertainty on the muon momentum scale, delta(pT_scale), are also correlated across bins. Uncorrelated uncertainties are due to the uncertainty from the muon resolution correction, delta(res), and the sample size of the signal Monte Carlo sample, delta(MC). The luminosity uncertainty 3.5% is not included.
