Oral report
The best understood mechanism for the generation of mass within the Standard Model is connected with the Higgs boson. Yet, alone, the Higgs can only explain a few percent of the proton mass. The remainder must be explained by another source. Contemporary theory indicates that the answer lies in nonlinear, nonperturbative phenomena within the gauge sector of quantum chromodynamics; indeed,...

Oral report
In 2010, a new method using muonic hydrogen spectroscopy led to a proton charge radius ($r_{p}$) result that was nearly ten times more precise but significantly smaller than results obtained using the two traditional methods, namely $e-p$ elastic scattering and ordinary Hydrogen spectroscopy. This discrepancy triggered the so-called "proton charge radius puzzle".
To investigate this...

中国极化电子-离子对撞机（EicC）项目是设想在将来建好的强流重离子加速器（HIAF）的基础上，进一步升级改造为电子-离子对撞机，为我国核物理和粒子物理以及相关科学领域提供大型综合实验平台。电子-离子对撞机，被称作当代卢瑟福散射实验，是人类认识物质世界深层次结构的理想工具。EicC实验将聚焦在研究核子的内部结构，尤其是海夸克部分子的分布，以及原子核内部的核子短程关联以及原子核介质的强相互作用性质。此外，EicC在研究研究重味奇特强子谱方面也具有独特的优势，这对于我们理解这些奇特强子态的性质具有极大的帮助。在本报告中，我将主要介绍EicC预研进展及在核子结构及强子物理方面的前景。

Oral report
The proposed STCF is a symmetric electron-positron beam collider designed to provide e+e− interactions at a centerof-mass energy from 2.0 to 7.0 GeV. The peaking luminosity is expected to be 0.5×10^35 cm−2s−1. The energy region of STCF covers the pair production thresholds for tau-leptons, charmed meson & baryons, and all of the strange hyperons. STCF is expected to deliver more than 1 ab−1 of...

Oral report
We investigate the inclusive and semi-inclusive productions of spin-3/2 hadrons, such as $\Omega$, in unpolarized $e^+ e^-$ annihilation. We derive a complete definition of quark transverse momentum dependent (TMD) fragmentation functions (FFs) to spin-3/2 hadrons for the first time from the decomposition of the quark-quark correlation matrix at leading twist, 14 of which are newly defined...

Oral report
Hadron spectroscopy provides direct physical measurements that shed light on the non-perturbative behavior of quantum chromodynamics (QCD). In particular, various exotic hadrons such as the newly observed $T_{cc}^+$ by the LHCb collaboration, offer unique insights into the QCD dynamics in hadron structures. In this letter, we demonstrate how heavy ion collisions can serve as a powerful venue...

Oral report
In the last two decades, many of the resonances observed in high energy collisions are incompatible with the traditional quark model, and those resonances are called the exotic states.
We depict those exotic states as the hadron-hadron molecule states and estimate the cross section for the production of the molecules in high energy collisions.
We predict a ground-state $D^+D^-$ hadronic...
