摘要

双离子干涉测量提供了在重离子碰撞中产生的源的空间和时间尺寸、形状和演化，为理论模型提供了强有力的约束。在这些论文集中，我们将报告相关强度（$\lambda $）和飞镜半径（${{R}_{text/{out}}}}}$, ${{R}_{text/{side}}}}}$、${{R}_{{text{long}}}}}$,$R_{{text{out}} - {\text{long}}}}^{2}$)是从Au + Au碰撞中的$\sqrt {{s}_{{NN}}}} $=3、3.2、3.5 和 3.9 GeV。将介绍这些参数对对横动量、对快速性、碰撞中心性和碰撞能量的依赖关系，并讨论它们的物理意义。

Identical Pion Interferometry from Au + Au Collisions at $\sqrt {{{s}_{{NN}}}} $ = 3, 3.2, 3.5, and 3.9 GeV in the STAR Experiment at RHIC

Two-pion interferometry provides access to the spatial and temporal size, shape, and evolution of the sources created in heavy ion collisions, offering strong constraints for theoretical models. In these proceedings, we will report the measurement of correlation strength ($\lambda $) and femtoscopic radii (${{R}_{{{\text{out}}}}}$, ${{R}_{{{\text{side}}}}}$, ${{R}_{{{\text{long}}}}}$, $R_{{{\text{out}} - {\text{long}}}}^{2}$) extracted from the two-pion correlation function in Au + Au collisions at $\sqrt {{{s}_{{NN}}}} $ = 3, 3.2, 3.5, and 3.9 GeV. The dependences of these parameters on pair transverse momentum, pair rapidity, collision centrality, and collision energy will be presented, and their physics implications will be discussed.

期刊介绍： The journal Fizika Elementarnykh Chastits i Atomnogo Yadr of the Joint Institute for Nuclear Research (JINR, Dubna) was founded by Academician N.N. Bogolyubov in August 1969. The Editors-in-chief of the journal were Academician N.N. Bogolyubov (1970–1992) and Academician A.M. Baldin (1992–2001). Its English translation, Physics of Particles and Nuclei, appears simultaneously with the original Russian-language edition. Published by leading physicists from the JINR member states, as well as by scientists from other countries, review articles in this journal examine problems of elementary particle physics, nuclear physics, condensed matter physics, experimental data processing, accelerators and related instrumentation ecology and radiology.
