Abstract

One of the primary goals of STAR’s experimental program at the Relativistic Heavy-Ion Collider (RHIC) is the investigation of Quantum chromodynamics (QCD) phase properties. These include the search for the location of QCD critical point and the predicted first order phase transition between Quark Gluon Plasma (QGP) and hadron gas. To make a detailed scan on the phase diagram, RHIC has performed two phases of the Beam Energy Scan program colliding gold nuclei at various nucleon-nucleon center of mass energies over the range from 62.4 to 7.7 GeV in BES-I, from 54.4 to 7.7 GeV in BES-II in collider mode and from 13.7 to 3 GeV in fixed-target (FXT) mode. This report will summarize some of the results obtained from BES-I and BES-II.

BES 计划的 STAR 实验结果
摘要 STAR 在相对论重离子对撞机(RHIC)上开展的实验计划的主要目标之一是研究量子色动力学(QCD)的相特性。其中包括寻找 QCD 临界点的位置,以及夸克胶子等离子体(QGP)和强子气体之间的一阶相变预测。为了对相图进行详细扫描,RHIC 已经执行了两个阶段的束能扫描计划,在 BES-I 对撞机模式下以不同的核子-核子质心能量在 62.4 到 7.7 GeV 范围内对撞金核,在 BES-II 对撞机模式下以对撞机模式在 54.4 到 7.7 GeV 范围内对撞金核,在固定目标(FXT)模式下以对撞机模式在 13.7 到 3 GeV 范围内对撞金核。本报告将总结 BES-I 和 BES-II 取得的一些结果。

期刊介绍: The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
