RHIC重离子碰撞中的喷流

Jets in heavy ion collisions at RHIC

Jan Kapitan

摘要:

重离子碰撞中的全喷注重建能够完整地研究由于热而致密的QCD物质中的能量损失而引起的喷流结构的改变,但是由于高多重性环境而具有挑战性。RHIC的STAR和PHENIX合作最近在$\sqrt{s_\mathrm{NN}} = 200 \mathrm{GeV}$上对p+p、Cu+Cu和Au+Au碰撞的完全重建喷流进行了测量。我们回顾了第一批结果包容射流光谱,双射流和破碎功能,并讨论其对理解射流淬火的影响。

英文摘要:

Full jet reconstruction in heavy-ion collisions enables a complete study of the modification of jet structure due to energy loss in hot and dense QCD matter, but is challenging due to the high multiplicity environment. The STAR and PHENIX collaborations at RHIC have recently presented measurements of fully reconstructed jets from p+p, Cu+Cu and Au+Au collisions at $\sqrt{s_\mathrm{NN}} = 200 \mathrm{GeV}$. We review the first results on inclusive jet spectra, di-jets and fragmentation functions and discuss their implications on understanding of jet quenching.
