用ALICE实验研究LHC能区Pb-Pb碰撞的第一事件涨落

First event-by-event fluctuation studies in Pb-Pb collisions at LHC energy by the ALICE experiment

Satyajit Jena

摘要:

相变的存在可以通过几个可观测量的特征行为来表现出来,这些可观测量可以从一个事件到另一个事件发生显著变化。因此,在逐事件的基础上研究各种守恒量为研究高密度物质的相变和性质提供了可能性。ALICE实验非常适合于对各种量进行精确的逐事件测量。本文介绍了由ALICE实验测量的平均横动量和净电荷分布的逐事件涨落。

英文摘要:

The presence of the phase transition can manifest itself by the characteristic behavior of several observables which may vary dramatically from one event to the other. Thus, the study of various conserved quantities on an event-by-event basis offers the possibility to study the phase transition and the nature of high density matter. The ALICE experiment is well suited for precise event-by-event measurements of various quantities. In this article, the event-by-event fluctuations of mean transverse momentum and net-charge distributions as measured by the ALICE experiment are presented.
