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…
Origin of the Covariant Wigner Operator as a Quantum Amplitude in QCD
Chueng-Ryong Ji, Daniel W. Piasecki
The Wigner function plays a central role in QCD as a phase space object encoding correlations among quarks, antiquarks, and gluons, yet its interpretation remains subtle due to its…
The Feynman path integral formulation of non-dispersive Airy wave packets and their applications to the heavy meson mass spectra and ultra-cold neutrons
Paul Ferrante, Connor Donovan, Chueng-Ryong Ji
We demonstrate the non-spreading behavior of Airy wave packets utilizing the Feynman path integral formulation of a linear potential, the Airy functions' zeros correspondence to he…
Nonlocal effective field theory and its applications
P. Wang, Zhengyang Gao, Fangcheng He +3
We review recent applications of nonlocal effective field theory, focusing in particular on nonlocal chiral effective theory and nonlocal quantum electrodynamics (QED), as well as…
Structure of lightest nuclei in the visible Universe
Satvir Kaur, Chandan Mondal, Xingbo Zhao +1
The simplest atomic nucleus, deuteron, provides key insights into the strong nuclear interactions among quarks and gluons that shape the visible universe. We present the first atte…
Nonlocal chiral contributions to generalized parton distributions of the proton at nonzero skewness
Zhengyang Gao, Fangcheng He, Chueng-Ryong Ji +3
We compute the one-loop contributions to spin-averaged generalized parton distributions (GPDs) in the proton from pseudoscalar mesons with intermediate octet and decuplet baryon st…
