Description

We present a study of parametrization dependence in the construction of the CT25M PDF uncertainty prescription. This prescription is informed by preliminary analyses within the CT collaboration, including investigations of general polynomial approximators for PDF modeling, statistical interpretations of model combination, and characterization of the solution space via clustering and information criteria. We summarize the key ingredients of this framework and review related studies within the CT group.
