The left upper plot shows the new track differential cross section. The error bars describe the uncertainty on the data points. This uncertainty includes the statistical uncertainty on the data and the statistical uncertainty on the total correction. In the plots at the bottom, the systematic and the total uncertainties are shown. The total uncertainty is the quadratic sum of the uncertainty reported on the data points and the systematic uncertainty. The right-hand-side plots show the same distributions but with a logarithmic horizontal scale. Refer to article [1] for explanations about the fit.
The left upper plot shows a comparison of the track differential cross section with the pythia prediction at hadron level (Tune A with ). The data error bars describe the uncertainty on the data points. This uncertainty includes the statistical uncertainty on the data and the statistical uncertainty on the total correction. The error bars on the simulation represent its statistical uncertainty. The ratio of data over prediction is shown in the lower plots. The right-hand-side plots show the same distributions but with a logarithmic horizontal scale.
