The proton mass, mp, is a defining scale in Nature. In fact, one understands the origin of almost all mass that is visible in the Universe if one grasps the source of mp. In modern high-energy physics, approximately 98% of mp is expected to be generated by Standard Model strong interactions, i.e., to emerge from quantum chromodynamics (QCD).

本次讲座将围绕“宇宙创生3分钟后发生了什么？”、“比铁更重的元素是如何产生的？”以及“宇宙中的碳氧比是如何形成的？”等关键问题展开讨论，并介绍相关领域的国际最新研究成果。在国家自然科学基金委重大项目的支持下，JUNA团队成功自主研发了全球领先的深地核物理实验装置，并发展出一种极低本底高效率的核天体物理反应测量方法，解决了近伽莫夫能量极低截面核天体反应直接测量这一重大难题。通过这些努力，研究团队排除了...

The quest of exotic hadrons with multiquark configuration beyond theconventional constituent quark model has been one of central subiects inhadron physics for decades. Among others, the doubly heavy tetraguarkcomposed of two heavy quarks and two light antiquarks attracts significantinterest, since it represents the simplest candidate with explicit multiguarkfeature and is expected to be bound u...

Under the relaxation time approximation of the Boltzmann equation, we compute the viscosities of the system to leading power in $T/\mu_B$ expansion and establish a relation between the thermodynamic potential and transport coefficients, including bulk viscosity ($\zeta$) and shear viscosity ($\eta$). It is found that hydrodynamic stability ($\zeta>0$) imposes additional constraints on the therm...

Title: Effects of Initial Nucleon-Nucleon Correlations on Light Nuclei Production in Au+Au Collisions at $\sqrt{s_{NN}}$=3 GeVSpeaker: Qian-Ru LinTime: 21 March (Friday) 2025, 2:00 pmLocation: 9627Abstract: Light nuclei production in heavy-ion collisions serves as a sensitive probe of the QCD phase structure. In coalescence models, triton (Nt) and deuteron (Nd) yields depend on the spatial sepa...
