标题： Methods to study event-by-event fluctuations in the NA61/SHINE experiment at the CERN SPS

摘要： 理论计算确定了强相互作用物质的临界点（CP）在CERN SPS可达到的能量范围内。逐事件的横向动量和多重数涨落被认为是寻找CP的最重要的工具之一。NA49实验进行了关于 $p_T$ 和多重数涨落的能量依赖性和系统大小依赖性的试点研究。NA61/SHINE离子计划是对此工作的延续。在简要回顾了NA49有关涨落的主要结果之后，我们将讨论我们计划应用于未来横向动量和多重数涨落分析的技术方法（去除非靶相互作用）。 显示英文摘要

摘要： Theoretical calculations locate the critical point of strongly interacting matter (CP) at energies accessible at the CERN SPS. Event-by-event transverse momentum and multiplicity fluctuations are considered as one of the most important tools to search for the CP. Pilot studies of the energy dependence and the system size dependence of both $p_T$ and multiplicity fluctuations were performed by the NA49 experiment. The NA61/SHINE ion program is a continuation of these efforts. After briefly recalling the essential NA49 results on fluctuations we will discuss the technical methods (removing Non-Target interactions) which we plan to apply for future transverse momentum and multiplicity fluctuation analyses.
