Iterated Agent for Symbolic Regression
Zhuo-Yang Song, Zeyu Cai, Shutao Zhang +8
Symbolic regression (SR), the automated discovery of mathematical expressions from data, is a cornerstone of scientific inquiry. However, it is often hindered by the combinatorial…
A generalized statistical model for fits to parton distributions
Mengshi Yan, Tie-Jiun Hou, Zhao Li +2
Parton distribution functions (PDFs) form an essential part of particle physics calculations. Currently, the most precise predictions for these non-perturbative functions are gener…
Impact of lattice gluon dataset on CTEQ-TEA global PDFs
Alim Ablat, Sayipjamal Dulat, Tie-Jiun Hou +3
We investigate the impact of the latest gluon parton results from lattice QCD on the global parton distribution function (PDF) analysis within the CTEQ-TEA framework. The dependenc…
The impact of LHC precision measurements of inclusive jet and dijet production on the CTEQ-TEA global PDF fit
Alim Ablat, Sayipjamal Dulat, Tie-Jiun Hou +5
In this study, we investigate the impact of new LHC inclusive jet and dijet measurements on parton distribution functions (PDFs) that describe the proton structure, with a particul…
New results in the CTEQ-TEA global analysis of parton distributions in the nucleon
A. Ablat, A. Courtoy, S. Dulat +11
This report summarizes the latest developments in the CTEQ-TEA global analysis of parton distribution functions (PDFs) in the nucleon. The focus is on recent NNLO fits to high-prec…
Progress in top-quark pair production cross section calculations and impact on parton distribution functions of the proton
Alim Ablat, Sayipjamal Dulat, Marco Guzzi +6
We discuss the impact of eligible top-quark pair production differential cross-section measurements at the LHC with a collision energy of 13 TeV on the parton distribution function…
