测试横向动量涨落的新的强强度测度

Testing new strongly intensive measures of transverse momentum fluctuations

Katarzyna Grebieszkow

摘要:

最近,人们提出了新的强强度涨落测度$Δ$和$Σ$。在本出版物中,它们的性质是使用事件的横向动量波动的例子进行测试。将获得的值与长期使用的pT波动的$Φ$测量进行比较。在快速生成器以及UrQMD模型产生的数据中进行了几次测试。本文给出了在CERN超级质子同步加速器上进行的NA 61/SHINE实验中所要研究的系统和能量的UrQMD计算。

英文摘要:

Recently, the new strongly intensive measures of fluctuations $Δ$ and $Σ$ have been proposed. In this publication their properties are tested using an example of event-by-event transverse momentum fluctuations. The obtained values are compared to the long used $Φ$ measure of pT fluctuations. Several tests are preformed within data produced by fast generators, as well as by the UrQMD model. The UrQMD calculations are presented for the systems and energies which are planned to be studied in the NA61/SHINE experiment at the CERN Super Proton Synchrotron.
