Exploring the neutron momentum distribution in nuclei through at an electron-positron collider
Zi-Wei Yan, Shu-man Hu, Wei Wang +3
The neutron momentum distribution is essential both for reliably extracting fundamental free neutron observables from nuclear measurements and for probing the tensor force via the…
Exploring Nucleon Structure through Sub- and Near-threshold -Meson Photoproduction
Wei Wang, Ji Xu, Xing-Hua Yang +2
We propose to investigate short-range correlations (SRCs) in nuclei by studying sub and near-threshold photoproduction of -meson. The feasibility of exploring this nuclear stru…
Probing the Core of Nuclear Structure through the Scattering at an Electron-Positron Collider
Wei Wang, Ji Xu, Ya-Teng Zhang +1
Short-range correlation pairs (SRCs) -- core of nuclear structure, composed of highly off-shell nucleons -- are mostly studied via electron-nucleon scattering, leaving a gap in mes…
A realistic method to access heavy meson light-cone distribution amplitudes from first-principle
Xue-Ying Han, Jun Hua, Xiangdong Ji +5
Lightcone distribution amplitudes (LCDAs) of heavy meson within heavy quark effective theory (HQET) are crucial for predicting physical observables in decays, but unfortunately…
Factorization Formula Connecting the Shape Functions of Heavy Meson in QCD and Heavy Quark Effective Theory
Wei Wang, Ji Xu, Qi-An Zhang +1
The shape function of -meson defined in heavy quark effective theory (HQET) plays a crucial role in the analysis of inclusive decays, and constitutes one of the dominant unc…
Linear relation between short range correlation and EMC effect of gluons in nuclei
Wei Wang, Ji Xu, Xing-Hua Yang +1
We explore the EMC effect of gluons through heavy quark production in deep inelastic scattering (DIS) and the nucleon-nucleon short range correlation (SRC) from sub-threshold photo…
