Valence Quark Distributions in Pions: Insights from Tsallis Entropy
Jingxuan Chen, Xiaopeng Wang, Yanbing Cai +2
We investigate the valence quark distributions of pions at a low initial scale () by employing Tsallis entropy, a non-extensive measure that effectively captures long-range…

An analysis of the gluon distribution with next-to-leading order splitting function in small-
Jingxuan Chen, Xiaopeng Wang, Yanbing Cai +2
An approximated solution for gluon distribution from DGLAP evolution equations with NLO splitting function in the small- limit is presented. We first obtain the simplified forms…

Fifth Force and Hyperfine Splitting in Muonic Atoms
Jingxuan Chen, Qian Wu, Xurong Chen +1
The potential existence of a fifth fundamental force, mediated by the X17 boson, has generated significant interest. This force can manifest itself as either a vector or pseudoscal…
