演講摘要:
相對論重離子對撞機(RHIC)為我們提供了相當豐富的量子色動力學(QCD)現象,特別是為我們研究QCD物質--在極高能量密度下產生的夸克膠子等離子體--提供了獨特的機會。另外,當前的宇宙射線實驗也有許多有趣且重要的結果。阿爾法磁譜儀(AMS-02)是太空中最強大的探測器之一,經過了8年的運作,也面臨著嚴峻的挑戰。本演講將介紹RHIC的重離子計畫及其目前狀態以及簡短更新AMS-02的實驗狀態。
In the past five decades, we had tremendous success in understanding our universe and how fundamental particles interact with each other. One of the most important tasks in physics is to have deeper insights into the detailed behavior of the strong interaction (Quantum ChromoDynamics, QCD). Relativistic Heavy-Ion Collider (RHIC) at Brookhaven National Laboratory provides us rich phenomena of QCD, in particular a unique opportunity for us to study the QCD matter, Quark Gluon plasma, which is created at extremely high energy density. On the other hand, there are many interesting and important results from the current cosmic ray experiments. Alpha Magnetic Spectrometer (AMS-02) is one of the most powerful detectors in space and it is facing a serious challenge after 8 years of operation. In this talk, I will give an introduction on the heavy-ion program and status at the RHIC and a short update on the AMS-02 experiment.
