Probing SU(2) Quark Flavor Asymmetry with W Bosons at RHIC

Maximiliano Ponce-Chavez

This work examines the effects of multiple parton radiation on proton-proton boson production at the Relativistic Heavy Ion Collider (RHIC), focusing on the ratio of charge…

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,…
