CTEQ-TEA group updates: Photon PDF and Impact from heavy flavors in the CT18 global analysis
Marco Guzzi, Keping Xie, Tie-Jiun Hou +4
We discuss recent CTEQ-TEA group activities after the publication of the CT18 global analysis of parton distribution functions (PDFs) in the proton. In particular, we discuss a new…
NNLO constraints on proton PDFs from the SeaQuest and STAR experiments and other developments in the CTEQ-TEA global analysis
Marco Guzzi, T. J. Hobbs, Tie-Jiun Hou +11
We review progress in the global QCD analysis by the CTEQ-TEA group since the publication of CT18 parton distribution functions (PDFs) in the proton. Specifically, we discuss compa…
The photon content of the proton in the CT18 global analysis
Keping Xie, T. J. Hobbs, Tie-Jiun Hou +3
Recently, two photon PDF sets based on implementations of the LUX ansatz into the CT18 global analysis were released. In CT18lux, the photon PDF is calculated directly using the LU…
The photon PDF within the CT18 global analysis
Keping Xie, T. J. Hobbs, Tie-Jiun Hou +3
Building upon the most recent CT18 global fit, we present a new calculation of the photon content of the proton based on an application of the LUX formalism. In this work, we explo…
Reduction of PDF uncertainty in the measurement of the weak mixing angle at the ATLAS experiment
Yao Fu, Siqi Yang, Minghui Liu +5
We investigate the parton distribution function (PDF) uncertainty in the measurement of the effective weak mixing angle at the CERN Large Hadron Colli…
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…
