在LHC处踏出T_c的邻域
Stepping outside the neighborhood of T_c at LHC
摘要：
“正如你所知道的，RHIC社区的许多人对LHC重离子计划感兴趣，但有几个问题：我们能在LHC学到什么新的东西？LHC中的碰撞是否与RHIC中的碰撞相似，只是初始状态更热/更密？若否，原因为何？这些问题是真诚地提出来的，这次演讲是一个直接向RHIC社区的大部分人回答这些问题的机会。“用这些话，在诺克斯维尔的夸克物质2009年的组织者邀请我讨论在大型强子对撞机上进行重离子碰撞的物理机会，而不回顾标准参数，这些参数主要基于机器的扩展运动学范围。作为回应，我在这里强调，格点量子色动力学表明在临界温度附近（T_c < T < 400 - 500 MeV）的热物理和在更高温度（T > 400-500 MeV）的热物理之间的特征性质的差异，对于更高温度，相关的能量密度将仅在LHC中获得。
英文摘要：
"As you are well aware, many in the RHIC community are interested in the LHC heavy-ion program, but have several questions: What can we learn at the LHC that is qualitatively new? Are collisions at LHC similar to RHIC ones, just with a somewhat hotter/denser initial state? If not, why not? These questions are asked in good faith, and this talk is an opportunity to answer them directly to much of the RHIC community." With these words, the organizers of Quark Matter 2009 in Knoxville invited me to discuss the physics opportunities for heavy ion collisions at the LHC without recalling the standard arguments, which are mainly based on the extended kinematic reach of the machine. In response, I emphasize here that lattice QCD indicates characteristic qualitative differences between thermal physics in the neighborhood of the critical temperature (T_c < T < 400 - 500 MeV) and thermal physics at higher temperatures (T > 400-500 MeV), for which the relevant energy densities will be solely attainable at the LHC.
