Strong Coupling Constant Determination from the new CTEQ-TEA Global QCD Analysis
Alim Ablat, Sayipjamal Dulat, Marco Guzzi +5
We present a new determination of the strong coupling constant from a global QCD analysis CT25 of parton distribution functions (PDFs) that incorporates high-precision exper…
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…
QED-enhanced PDF implications for the Higgs sector
Amanda M. Cooper-Sarkar, Thomas Cridge, T. J. Hobbs +4
In this work, we examine the implications of electroweak corrections beyond leading order for processes of special interest in the Higgs sector. We especially explore the role of t…
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,…
