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…
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 Strangeness Asymmetry Data in the CTEQ-TEA Global Analysis
Tie-Jiun Hou, Huey-Wen Lin, Mengshi Yan +1
We study the impact of lattice data on the determination of the strangeness asymmetry distribution in the general CTEQ-TEA global analysis of par…
Connected and Disconnected Sea Partons from CT18 Parametrization of PDFs
Tie-Jiun Hou, Mengshi Yan, Jian Liang +2
The separation of the connected and disconnected sea partons, which were uncovered in the Euclidean path-integral formulation of the hadronic tensor, is accommodated with an altern…
A CT18 global PDF fit at the leading order in QCD
Mengshi Yan, Tie-Jiun Hou, Pavel Nadolsky +1
In this paper, we present a CT18 PDFs fitted with Leading-Order QCD perturbation theory. The CT18 LO PDFs is obtained within the general CT18 framework, along with two additional t…
Parton distributions need representative sampling
Aurore Courtoy, Joey Huston, Pavel Nadolsky +3
In global QCD fits of parton distribution functions (PDFs), a large part of the estimated uncertainty on the PDFs originates from the choices of parametric functional forms and fit…
Impact of lattice data in the CTEQ-TEA global analysis
Tie-Jiun Hou, Huey-Wen Lin, Mengshi Yan +1
We study the impact of the lattice data on the determination of the strangeness asymmetry distribution in the general CTEQ-TEA global analysis of…
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…
Connected and Disconnected Sea Partons from CT18 Parametrization of PDFs
Tie-Jiun Hou, Jian Liang, Keh-Fei Liu +2
The separation of the connected and disconnected sea partons, which were uncovered in the Euclidean path-integral formulation of the hadronic tensor, is accommodated with the CT18…
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…
Determining the helicity structure of the nucleon at the Electron Ion Collider in China
Daniele Paolo Anderle, Tie-Jiun Hou, Hongxi Xing +3
Understanding how sea quarks behave inside a nucleon is one of the most important physics goals of the proposed Electron-Ion Collider in China (EicC), which is designed to have 3.5…
Electron-Ion Collider in China
Daniele P. Anderle, Valerio Bertone, Xu Cao +99
Lepton scattering is an established ideal tool for studying inner structure of small particles such as nucleons as well as nuclei. As a future high energy nuclear physics project,…
