Nucleon Strong-Interactions Size From Charmonium Photoproduction

Xiangdong Ji, Sylvester Joosten, Zein-Eddine Meziani +1

Protons and neutrons differ dramatically in their electromagnetic sizes, but are bound by the strong (color) force and have nearly identical masses, like two twin states of the sam…

Percent-Level Prediction of the Deuteron Magnetic Polarizability

Rishi Cherukuri, Jiunn-Wei Chen, Xiangdong Ji

Working through next-to-next-to-leading order (NNLO) accuracy in pionless effective field theory, we compute the isovector magnetic-dipole contribution to the scalar deuteron magne…

Evidence for Quark Confinement in the Proton

Xiangdong Ji, Gerald A. Miller, Chen Yang

The strong interaction is the fundamental force that holds quarks and the gluon force carriers together to form protons and neutrons and also binds the atomic nucleus. The theory g…

Quark Imaging in the Proton Via Quantum Phase-Space Distributions

A. V. Belitsky, Xiangdong Ji, Feng Yuan

We develop the concept of quantum phase-space (Wigner) distributions for quarks and gluons in the proton. To appreciate their physical content, we analyze the contraints from speci…

Chiral structure of nucleon gravitational form factors

A. V. Belitsky, X. Ji

We study the low momentum behavior of nucleon gravitational form factors in the framework of the heavy baryon chiral perturbation theory. At zero recoil they determine the momentum…

Constructing Parton Convolution in Effective Field Theory

Jiunn-Wei Chen, Xiangdong Ji

Parton convolution models have been used extensively in describing the sea quarks in the nucleon and explaining quark distributions in nuclei (the EMC effect). From effective field…

Studying Hadronic Structure of the Photon in Lattice QCD

Xiangdong Ji, Chulwoo Jung

We show that the matrix element of a local quark-gluon operator in the photon state, , can be calculated in lattice QCD. The result is generalized to other q…

The Spin Structure of the Nucleon

B. W. Filippone, Xiangdong Ji

We present an overview of recent experimental and theoretical advances in our understanding of the spin structure of protons and neutrons.

Comment on "Complete One-Loop Analysis of the Nucleon's Spin Polarisabilities"

Michael C. Birse, Xiangdong Ji, Judith A. McGovern

We comment on the paper of Gellas et al, nucl-th/0002027, in which heavy baryon chiral perturbation theory results for the spin polarisabilities of the nucleon are given. That pape…

Measuring the P-odd Pion-Nucleon Coupling h_{πNN}^{(1)} in π^+ Photoproton Production Near the Threshold

Jiunn-Wei Chen, Xiangdong Ji

We show that polarized gamma p -> π^+ n in the threshold region is an excellent candidate for measuring the leading parity-violating pion-nucleon coupling h_{πNN}^{(1)} to an uncer…
