Constraints on pion parton distributions at small from leading-neutron electroproduction data
C. Yang, P. C. Barry, W. Melnitchouk +1
We revisit the extraction of parton distribution functions (PDFs) in the pion in a global QCD analysis of pion--nucleus Drell--Yan and leading-neutron (LN) electroproduction data,…
Event-Level QCD Inference Framework for Quark-Gluon Imaging
Patrick Barry, Pi-Yueh Chuang, Ian Cloët +3
We introduce and demonstrate an event-level analysis framework for quark-gluon imaging. For a first application we use it for the inference of parton distribution functions from sy…
First simultaneous analysis of transverse momentum dependent and collinear parton distributions in the proton
P. C. Barry, A. Prokudin, T. Anderson +9
We present the first simultaneous global QCD analysis of unpolarized transverse momentum dependent (TMD) and collinear parton distribution functions (PDFs) in the proton. Our study…
First simultaneous global QCD analysis of kaon and pion parton distributions with lattice QCD constraints
P. C. Barry, Chueng-Ryong Ji, W. Melnitchouk +2
We perform the first simultaneous global QCD analysis of pion and kaon parton distribution functions (PDFs), constrained by pion- and kaon-induced Drell-Yan (DY) and leading neutro…
Pionic gluons from global QCD analysis of experimental and lattice data
William Good, Patrick C. Barry, Huey-Wen Lin +3
We perform the first global QCD analysis of parton distribution functions (PDFs) in the pion, with lattice-QCD data on gluonic pseudo--Ioffe-time distributions fitted simultaneousl…
Strong Interaction Physics at the Luminosity Frontier with 22 GeV Electrons at Jefferson Lab
A. Accardi, P. Achenbach, D. Adhikari +441
This document presents the initial scientific case for upgrading the Continuous Electron Beam Accelerator Facility (CEBAF) at Jefferson Lab (JLab) to 22 GeV. It is the result of a…
Tomography of pions and protons via transverse momentum dependent distributions
P. C. Barry, L. Gamberg, W. Melnitchouk +4
We perform the first simultaneous extraction of parton collinear and transverse degrees of freedom from low-energy fixed-target Drell-Yan data in order to compare the transverse mo…
Complementarity of experimental and lattice QCD data on pion parton distributions
P. C. Barry, C. Egerer, J. Karpie +8
We extract pion parton distribution functions (PDFs) in a Monte Carlo global QCD analysis of experimental data together with reduced Ioffe time pseudo-distributions and matrix elem…
Global QCD Analysis of Pion Parton Distributions with Threshold Resummation
P. C. Barry, Chueng-Ryong Ji, N. Sato +1
We perform the first global QCD analysis of pion valence, sea quark, and gluon distributions within a Bayesian Monte Carlo framework with threshold resummation on Drell-Yan cross s…
Science Requirements and Detector Concepts for the Electron-Ion Collider: EIC Yellow Report
R. Abdul Khalek, A. Accardi, J. Adam +410
This report describes the physics case, the resulting detector requirements, and the evolving detector concepts for the experimental program at the Electron-Ion Collider (EIC). The…
Towards the three-dimensional parton structure of the pion: Integrating transverse momentum data into global QCD analysis
N. Y. Cao, P. C. Barry, N. Sato +1
We perform a new Monte Carlo QCD analysis of pion parton distribution functions, including, for the first time, transverse momentum dependent pion-nucleus Drell-Yan cross sections…
Revealing the structure of light pseudoscalar mesons at the Electron-Ion Collider
John Arrington, Carlos Ayerbe Gayoso, Patrick C Barry +29
How the bulk of the Universe's visible mass emerges and how it is manifest in the existence and properties of hadrons are profound questions that probe into the heart of strongly i…
First Monte Carlo global QCD analysis of pion parton distributions
P. C. Barry, N. Sato, W. Melnitchouk +1
We perform the first global QCD analysis of parton distribution functions (PDFs) in the pion, combining Drell-Yan data with leading neutron electroproduction from HERA within…
