Generator Tuning Validation
Note: this view is still in a development stage. Exercise care and common sense when interpreting results.
Use this view to compare different tunes of a generator (tuning validation).
Numbers in the tables correspond to chi2 values. To make them more physically meaningful, the MC predictions are assigned a flat 5% 'theory uncertainty', as a baseline sanity limit for the achievable theoretical accuracy with present-day MC models. A few clear cases of GIGO are excluded, but some problematic cases remain. Thus, e.g., if a calculation returns a too small cross section for a dimensionful quantity, the corresponding chi2 value will be large, even though the shape of the distribution may be well described. The interpretation of the information we display is up to you, the user.
