On the Model Dependence of Fiducial Cross Section Measurements in View of Reinterpretations

Understand

Fiducial production cross sections measurements of Standard Model processes, in principle, provide constraints on new physics scenarios via a comparison of the predicted Standard Model cross section and the observed cross section.

• This approach received significant attention in recent years, both from direct constraints on specific models and the interpretation of measurements in the view of effective field theories.
• A generic problem in the reinterpretations of Standard Model measurements is the corrections applied to data to account for detector effects.
• These corrections inherently assume the Standard Model to be valid, thus implying a model bias of the final result.
