Measurements

To be useful in our approach, measurements must be made in as model-independent a fashion as possible.

Cross sections should be measured in a kinematic region closely matching the detector acceptance — commonly called ’fiducial cross sections’ — to avoid extrapolation into unmeasured regions. This is because such extrapolations must always make theoretical assumptions; usually that the SM is valid in the unmeasured region.

The measurements should generally be made in terms of observable final state particles (e.g. leptons, photons) or objects constructed from such particles (e.g.hadronic jets, missing energy) rather than assumed intermediate states (\(W, Z, H\), top).

Finally, differential measurements are most reliable for Contur, as features in the shapes of distributions are usually more robust against theory uncertainties than simple event rates – especially when error correlation information is provided by the experiments.

The measurements are split into statistically orthogonal data sets (analysis pools), based upon experiment, beam energy and final state.

Ratio measurements

These typically use SM theory for the denominator, and may give unreliable results if your model contributes to both numerator and denominator. On by default, can be turned off via command-line.

Pool: ATLAS_13_METJET missing transverse momentum plus jets

Higgs to diphotons

Higgs to two photons use a data-driven background subtraction. If your model predicts non-resonant photon production this may lead to unreliable results. On by default, can be turned off via command-line.

Searches

Detector-level, using Rivet smearing functions. Off by default, can be turned on via command-line.

Typically involve large data-driven top background subtraction. If your model contributes to the background as well the results maybe unreliable. Off by default, can be turned on via command-line.

b-jet veto issue

The following measurements apply a detector-level b-jet veto which is not part of the particle-level fiducial definition and therefore not applied in Rivet. Also applies to CMS Higgs-to-WW analysis. Off by default, can be turned on via command-line, but use with care.
