AI 中文总结

介绍欧洲核子研究中心超级质子同步加速器(CERN SPS)的未来固定靶计划,其是QGP实验研究开端,已取得诸多成果。目前加速器关闭后QGP研究将继续,涉及NA61等实验,还将讨论新测量及其对QGP知识在特定区域的影响。

AI 中文摘要

欧洲核子研究中心的超级质子同步加速器(SPS)目前可将重离子加速至13.5到150 A GeV能量范围并用于固定靶实验,这里是1986年夸克-胶子等离子体(QGP)实验研究的开端。2000年前的第一阶段有多项重要发现,之后物理计划通过NA60(2003 - 2004年的双轻子实验)和NA61(2009年起的强子可观测量实验)延续至今。目前欧洲核子研究中心加速器关闭后,预计QGP研究将继续,涉及NA61和新批准的NA60 + / DiCE实验。本文将简要描述CERN SPS计划的主要成就,讨论新提议的测量及其对我们在QCD相图有限\(\mu_{\rm B}\)区域中QGP知识的影响。

英文摘要

The CERN Super Proton Synchrotron (SPS) can currently accelerate heavy ions in the energy range from 13.5 up to 150 A GeV and deliver them to fixed-target experiments. It is the facility where Quark-Gluon Plasma (QGP) experimental studies began in 1986. After a first phase until 2000, with several fundamental discoveries made by a number of dedicated experiments, the physics program continued until today with the NA60 (dileptons, 2003-2004) and NA61 (hadronic observables, from 2009) experiments. As of today, a continuation of QGP studies, after the current shutdown of CERN accelerators, is foreseen, involving NA61 and a newly approved experiments, NA60+/DiCE. In this contribution, I will briefly describe the main achievements of the CERN SPS program, discuss the proposed new measurements and their impact on our knowledge of the QGP in the finite $μ_{\rm B}$ region of the QCD phase diagram.
