Abstract

Properties of nuclear matter can be studied by relativistic heavy-ion collisions in high-energy experiments like STAR. One of the methods to learn about properties of nuclear matter is femtoscopy, which relies on information carried by particles produced in the collisions. Using femtoscopic observables, space-time characteristics of the source can be extracted. During heavy-ion collisions mostly pions are produced, and therefore pion femtoscopy is a particularly useful tool. High statistics data sets from RHIC have also made it possible to study the strange particle correlations. The lightest strange hadrons are charged and neutral kaons. The strong interaction, which conserves the strangeness quantum number, is responsible for the kaon production. It is possible to study the neutral kaons, \(K_{S}^{0}\), which can be measured through their decay products to charged pions. In these proceedings, one-dimensional correlation functions of neutral kaon pairs in Au + Au collisions at \(\sqrt {{{s}_{{NN}}}} \) = 200 GeV measured by the STAR experiment at RHIC are presented.

摘要

可以通过相对论重离子碰撞（例如STAR）在高能实验中研究核物质的性质。核磁共振检查法是了解核物质特性的一种方法，它依靠碰撞中产生的粒子携带的信息。使用femtoscopic观察物，可以提取源的时空特征。在重离子碰撞过程中，大多数会产生离子，因此离子飞灰检查是一种特别有用的工具。RHIC的高统计数据集也使研究奇怪的粒子相关性成为可能。最轻的奇怪强子是带电的和中性的凯恩斯。保持奇异量子数的强相互作用是产生kaon的原因。可以研究中性的kaons \（K_ {S} ^ {0} \），可以通过它们对带电介子的衰变产物进行测量。在这些程序中，提出了通过RHIC的STAR实验测得的\（\ sqrt {{{s __ {{{NN}}}} \） = 200 GeV下Au + Au碰撞中的中性钾对的一维相关函数。。
