The four experiments at the LHC test QCD predictions with their measurements in ultra-relativistic  proton—proton (pp),  proton—nucleus and nucleus—nucleus collisions, and in particular, they are interested in the measurement of the properties of the quark-gluon plasma (QGP) created in heavy-...

Quantum Chromodynamics (OCD), the fundamental theory of the strong interaction; predicts a rich phase structure of matter under extreme conditions of temperature and density. Understanding phase transitions in strongly interacting matter is central to exploring the behavior of QCD in such ...

Recent CMS data have revealed long-range correlations at high charged particle multiplicity (N_ch^j) within jets produced in proton-proton (pp) collisions, suggesting collective behavior in systems much smaller than those typical of heavy ion collisions. In the polar coordinate system about the reconstructed ...

质子是宇宙的基石之一。质子由夸克胶子组成。胶子分布支配了高能强子碰撞的行为。多年前OCD演化方程研究预言胶子在小x区会发生凝聚。受能量守恒和相对论协变的约束，凝聚胶子会使质子碰撞产生的伽马射线能谱呈现特有的折断幂律，这预言被最近记录到的千年一遇的伽马爆 GRB221009A完美地证实。由此可能打开一条连接微观与宇观的新通道。报告人简介朱伟，...
