介绍了在星星上用已识别粒子进行的新的物理结果。测量在低pT地址散装属性的碰撞，而那些在高pT地址喷射能量损失的散装物质生产。在这些极端情况之间，在中间pT的测量解决了射流和本体之间的相互作用。我们强调：作为初始条件和状态方程的一种新的灵敏探针的v2涨落的测量;涉及多个奇异粒子的关联，沿着被识别粒子的比率以测试聚结作为在中间pT的粒子产生的机制;三粒子方位角关联以搜索锥形发射;以及高pT下强子产生的能量和粒子类型依赖性，以研究夸克和胶子喷注能量损失。
New physics results with identified particles at STAR are presented. Measurements at low pT address bulk properties of the collision, while those at high pT address jet energy loss in the bulk matter produced. Between these extremes, measurements at intermediate pT address the interplay between jets and the bulk. We highlight: measurements of v2 fluctuations as a new, sensitive probe of the initial conditions and the equation of state; correlations involving multi-strange particles, along with ratios of identified particles to test coalescence as a mechanism of particle production at intermediate pT; three particle azimuthal correlation to search for conical emission; and the energy and particle-type dependence of hadron production at high pT to study quark and gluon jet energy loss.
