质子累积量和关联函数的快度依赖性

Rapidity dependence of proton cumulants and correlation functions

Adam Bzdak, Volker Koch

摘要:

研究了多质子关联函数和累积量对快度和横动量接受度的依赖关系。我们发现,在误差范围内,各种累积量比的初步数据与快度和横动量无关的关联函数是一致的。然而,随着质子之间的快度分离而适度增加的快度相关稍微有利。我们建议进一步探索多粒子关联函数的快度依赖性,通过测量作为快度窗口的大小的函数的集成约化关联函数的依赖性。

英文摘要:

The dependence of multi-proton correlation functions and cumulants on the acceptance in rapidity and transverse momentum is studied. We find that the preliminary data of various cumulant ratios are consistent, within errors, with rapidity and transverse momentum independent correlation functions. However, rapidity correlations which moderately increase with rapidity separation between protons are slightly favored. We propose to further explore the rapidity dependence of multi-particle correlation functions by measuring the dependence of the integrated reduced correlation functions as a function of the size of the rapidity window.
