Abstract Lepton scattering is an established ideal tool for studying inner structure of small particles such as nucleons well nuclei. As a future high energy nuclear physics project, Electron-ion collider in China (EicC) has been proposed. It will be constructed based on upgraded heavy-ion accelerator, High Intensity Accelerator Facility (HIAF) which currently under construction, together with new electron ring. The proposed provide highly polarized electrons (with polarization ∼80%) and...

Exploring the nature of exotic multiquark candidates such as X(3872) plays a pivotal role in understanding quantum chromodynamics (QCD). Despite significant efforts, consensus on their internal structures is still lacking. As prime example, it remains pressing open question to decipher state between two popular configurations: loose hadronic molecule or compact tetraquark. We demonstrate novel approach help address this problem by studying production heavy ion collisions, where hot fireball...

Relativistic heavy-ion experiments have observed similar quenching effects for (prompt) $D$ mesons compared to charged hadrons transverse momenta larger than 6-8~GeV, which remains a mystery since heavy quarks typically lose less energies in quark-gluon plasma light and gluons. Recent measurements of the nuclear modification factors $B$ $B$-decayed by CMS Collaboration provide unique opportunity study flavor hierarchy jet quenching.

A set of quasi-parton distribution functions (quasi-PDFs) have been recently proposed by Ji. Defined as the matrix elements equal-time spatial correlations, they can be computed on lattice and should reduce to standard PDFs when proton momentum $P_z$ is very large. Since taking $P_z\to \infty$ limit not feasible in simulations, it essential provide guidance for what values quasi-PDFs are good approximations PDFs. Within framework spectator diquark model, we evaluate both up down quarks' all...
