论文摘要
我们对精选主题的热和密集QCD问题的最新状态进行了理论和实验摘要。我们回顾了QCD相图的光束能量扫描程序，并介绍了搜索QCD临界点的当前状态，高巴里亚密度区域中的颗粒产生，超核产生和全局极化在核核碰撞中的影响。陌生部门中的可用实验数据表明，高碰撞能量下热模型中的大规范方法使低能处的规范集合行为过渡。我们进一步讨论了核冲突的未来前景，以探究富含巴能的物质的特性。在高温和低巴属密度下创建夸克 - 杜伦等离子体已被称为“小爆炸”，类似地，在较低碰撞能量时，少量富含巴属物质的femtoter尺寸可以称为“ femto-nova”，这可能是可维持的，它可能维持非先进的旋转和磁场。
We make a theoretical and experimental summary of the state-of-the-art status of hot and dense QCD matter studies on selected topics. We review the Beam Energy Scan program for the QCD phase diagram and present the current status of search for QCD Critical Point, particle production in high baryon density region, hypernuclei production, and global polarization effects in nucleus-nucleus collisions. The available experimental data in the strangeness sector suggests that a grand canonical approach in thermal model at high collision energy makes a transition to the canonical ensemble behavior at low energy. We further discuss future prospects of nuclear collisions to probe properties of baryon-rich matter. Creation of a quark-gluon plasma at high temperature and low baryon density has been called the "Little-Bang" and, analogously, a femtometer-scale explosion of baryon-rich matter at lower collision energy could be called the "Femto-Nova", which may possibly sustain substantial vorticity and magnetic field for non-head-on collisions.
