LHC and DIS experimental data in the CT18(Z) global QCD analysis

29 Aug 2019 · Hou Tie-Jiun, Xie Keping, Gao Jun, Dulat Sayipjamal, Guzzi Marco, Hobbs T. J., Huston Joey, Nadolsky Pavel, Pumplin Jon, Schmidt Carl, Sitiwaldi Ibrahim, Stump Dan, Wang Bo-Ting, Yuan C. -P. ·

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 strength. New methodological developments in the fitting methodology are discussed. Behavior of the CT18 NNLO PDFs for the conventional and "saturation-inspired" factorization scales in deep-inelastic scattering is reviewed. Four new families of (N)NLO CTEQ-TEA PDFs are presented: CT18, A, X, and Z.
