New CTEQ global analysis of quantum chromodynamics with high-precision data from the LHC
Tie-Jiun Hou, Jun Gao, T. J. Hobbs +10
We present the new parton distribution functions (PDFs) from the CTEQ-TEA collaboration, obtained using a wide variety of high-precision Large Hadron Collider (LHC) data, in additi…
LHC and DIS experimental data in the CT18(Z) global QCD analysis
Tie-Jiun Hou, Keping Xie, Jun Gao +11
We discuss implementation of the LHC experimental data sets in the new CT18 global analysis of quantum chromodynamics (QCD) at the next-to-next-leading order of the QCD coupling st…
Progress in the CTEQ-TEA NNLO global QCD analysis
Tie-Jiun Hou, Keping Xie, Jun Gao +10
We present the new CTEQ-TEA global analysis of quantum chromodynamics (QCD). In this analysis, parton distribution functions (PDFs) of the nucleon are determined within the Hessian…

Impact of LHC top-quark pair measurements to CTEQ-TEA PDF analysis
Orkash Amat, Michał Czakon, Sayipjamal Dulat +9
Detailed studies have been carried out on the impact of the LHC top quark pair production data on gluon PDF, in the context of the CTEQ-TEA global PDF fit, with the ePump-updating…
Updating and Optimizing Error PDFs in the Hessian Approach. Part II
Tie-Jiun Hou, Zhite Yu, Sayipjamal Dulat +2
In an earlier publication, we introduced the software package, {\tt \texttt{ePump}} (error PDF Updating Method Package), that can be used to update or optimize a set of parton dist…
