Abstract

The correlation femtoscopy allows one to measure the space-time characteristics of particle production processes due to the effects of quantum statistics (QS) and final state interactions (FSI). Femtoscopy at lower energies was intensively studied at AGS, SPS and in the Beam Energy Scan (BES) program at RHIC. In the work we discuss possibilities to observe a difference from the first-order phase transition expected, according some theoretical predictions, at low energies and the crossover one, to be occurred at high energies, with the femtoscopy observables using the hybrid model vHLLE + UrQMD. The possibilities to use kaon femtoscopy complementary to the usually used pion one are discussed.

摘要

由于量子统计（QS）和最终状态相互作用（FSI）的影响，相关功能学使人们能够测量颗粒生产过程的时空特性。在AGS，SPS以及RHIC的束能量扫描（BES）程序中，都对低能量的窥镜检查进行了深入研究。在工作中，我们讨论了根据一些理论预测在低能量下观察到的与预期的一阶相变之间的差异的可能性，以及在混合动力模型vHLLE + UrQMD观察下的窥镜检查下，观察到的在高能量下发生的交叉相变。 。讨论了使用kaon肺部窥镜检查补充通常使用的pion的可能性。
