The errors shown here are the statistical errors reported by the fitter (ROOT's standard chi^2 fit). They are superceded by the statistical errors from the ensemble testing, which are significantly bigger.

This shows that the data is only consistent with our model when the systematic uncertainties are taken into account. Arguably, the model uncertainties should not be included in this comparison, how ever this has little effect. The choice of SM model is not crucial. All the above are not surprising given the input data and SM models - see Jim's data plot #1, data plot #2, and uncertainties page. On the other hand, some features are noteworthy for what they tell us of the data. Namely, the large difference between the two test statistics in the data (indicating that the data comes from a different distribution?) and the overall level of agreements between data and SM models.

BTW: We should improve data plot #2,

BTW: the points missing from the no-systematics plot are missing because I didn't generate them. Can be easily fixed if there's any reason to do so.

Notes:
  • the CLs limit at 4.2TeV is very doubtful (~50% chance of it not really being there, in which case it may lie lower and may not exist at all).
  • the CLs limit at 4.05TeV appears low in this plot. In fact, there's about a 50% chance that it belongs at -2.645 (which is still below the data, but makes a nicer straight line).
  • the existence of the CLs limit at 4.1TeV is driven by the point plotted - our confidence is about 1.5 sigma in MC statistic - again, this is a harder question than whether we exclude this lambda value)
  • These and other details are available in https://twiki.cern.ch/twiki/bin/view/Main/AmnonHarelCLsInDCR#Final_results

Presentation:

Present as a Z-plot with only the point at 4.05TeV? More conservative - show 4.05 and 4.1. We have an answer ready if people within and outside CMS want to know more. No one said we got to have a short answer to people who are trying to 2nd guess us.

Technical tests

Systematic variations output from the statistics code

The following plots shows the systematic variations possible in the statistics code. In the limit setting, NPcorr and PDF are used as flat uncertainties. Their full shapes are only used in the QCD ensembles for the p-values. Similarly, the QCD model systematic is only used in limit setting (it's |Pythia-NLOcorr|).
