Fantômas: An analysis of parton distributions in a pion with Bézier parametrizations
Lucas Kotz, Aurore Courtoy, Pavel Nadolsky +2
We systematically explore the parametrization dependence of the Parton Distribution Functions (PDFs) to better quantify the true uncertainty from global QCD analyses. To achieve th…

Fantômas Unconfined: global QCD fits with Bézier parameterizations
Lucas Kotz, Aurore Courtoy, T. J. Hobbs +4
Fantômas is a C++ toolkit for exploring the parametrization dependence of parton distribution functions (PDFs) and other correlator functions in quantum chromodynamics (QCD). Fantô…

Fantômas4QCD: pion PDFs with epistemic uncertainties
Aurore Courtoy, Lucas Kotz, Pavel Nadolsky +2
In these proceedings, we reiterate and extend the discussion of the Next-to-Leading Order (NLO) QCD analysis of the charged pion Parton Distribution Function (PDF) obtained within…
