论文摘要
对高能碰撞中的触发性相关性的研究是研究在这种碰撞中形成的粒子发射区域的时空结构的强大工具，以及探测涉及粒子在发射后可能会发生的相互作用。概述了使用带电颗粒的两粒子触发相关性测量结果的CMS实验的最新结果，并在PP和PBPB碰撞中鉴定出了Hadron。通常，假设高斯或指数形状来描述发射源分布，则获得featsoscotic参数。但是，在某些情况下，广义高斯（即对称α稳定的lévy分布）很喜欢描述来源。其中一些测量值允许使用其featsoscopic相关性提取Hadron所感受到的强相互作用的参数。研究以众多的平均横向动量（或平均横向质量）和带电的粒子多重性进行。此外，还讨论了使用CMS实验的未来物理结果的前景。
The study of femtoscopic correlations in high-energy collisions is a powerful tool to investigate the space-time structure of the particle emitting region formed in such collisions, as well as to probe interactions that the involved particles may undergo after being emitted. An overview of the recent results from the CMS experiment at the LHC on the two-particle femtoscopic correlations measurements using charged particles and identified hadrons in pp and PbPb collisions is presented. In general, the femtoscopic parameters are obtained assuming a Gaussian or an exponential shape to describe the emitting source distribution. In some cases, however, the generalized Gaussian, i.e., the symmetric alpha-stable Lévy distribution, is favored to describe the source. Some of the measurements allow to extract the parameters of the strong interaction felt by hadrons using their femtoscopic correlations. The studies are performed in a wide range of the pair average transverse momentum (or average transverse mass) and charged particle multiplicities. In addition, prospects for future physics results using the CMS experiment are also discussed.
