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…
Determination of heavy meson light-cone distribution amplitudes: theoretical framework and lattice simulations
Hao-Fei Gao, Xue-Ying Han, Jun Hua +15
We present a first-principles determination of heavy meson light-cone distribution amplitudes (LCDAs) from lattice QCD in the continuum limit, improving substantially on our previo…
Automated Extraction of Collins-Soper Kernel from Lattice QCD using An Autonomous AI Physicist System
Jin-Xin Tan, Ting-Jia Miao, Mu-Hua Zhang +5
We employ {PhysMaster}, an autonomous agentic AI system integrating theoretical reasoning, numerical computation, and exploitation strategies towards ultra-long horizon automation,…
A Lattice QCD study of scattering in continuum and chiral limits
Hang Liu, Liuming Liu, Jin-Xin Tan +3
We present a first systematic study of proton- (-) scattering from lattice QCD, using seven sets of -flavor lattice ensembles with pion masses spanning 13…
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…
