Pion and Kaon PDFs via Infrared-Safe Evolution augmented by Data Constraints
Yanbing Cai, Chengdong Han, Xurong Chen
Probing the partonic structure of the pion and the kaon provides essential insights into the non-perturbative dynamics of QCD, yet their parton distribution functions (PDFs) remain…
A practical methodology for global polarization extraction in fixed-target experiments
Tan Lu, Chengdong Han, Chenlu Hu +7
Non-central heavy-ion collisions generate large orbital angular momentum in the created medium, which leads to polarization of final-state particles via spin-orbit coupling, known…
Neutron structure function via a maximum entropy analysis
Chengdong Han, Rong Wang, Xurong Chen
We employ the maximum entropy method to extract the valence quark distributions of the neutron at a low scale, \( Q_0^2 \). At this initial scale, the neutron is defined to contain…
First Extraction of the - scattering length from near-threshold photoproduction on helium-4
Chengdong Han, Wei Kou, Rong Wang +1
We present a model-independent extraction of the phi-4He scattering length from near-threshold phi photoproduction on helium-4, based on LEPS Collaboration data for the coherent pr…
High Behavior of the Proton Structure Function through the Balitsky-Kovchegov Equation
Wei Kou, Gang Xie, Xiaopeng Wang +2
Numerous experimental and theoretical investigations have highlighted the power law behavior of the proton structure function , particularly the dependence of its po…
