CT25: Progress toward next-generation PDFs for precision phenomenology at the LHC
A. Ablat, A. Courtoy, S. Dulat +10
We summarize recent progress toward the next generation of CTEQ-TEA parton distribution functions, CT25, based on a global NNLO analysis that incorporates a significant sample of n…
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…
Information Criteria for Selecting Parton Distribution Function Solutions
Aurore Courtoy, Arturo Ibsen
In data-driven determination of Parton Distribution Functions (PDFs) in global QCD analyses, uncovering the true underlying distributions is complicated by a highly convoluted inve…
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). Fant…
Fantômas: epistemic and nuclear uncertainties for the parton distributions of the pion
Lucas Kotz, Aurore Courtoy, Pavel Nadolsky +1
We present Fanto10, a new ensemble of NLO error parton distribution functions (PDFs) in a charged pion that provides the most detailed estimate of uncertainties from experimental,…
QCD factorization with multihadron fragmentation functions
T. C. Rogers, M. Radici, A. Courtoy +1
Important aspects of QCD factorization theorems are the properties of the objects involved that can be identified as universal. One example is that the definitions of parton densit…
