论文摘要
在\ rootsnn = 5.02 tev的框架内提出了PB $ -PB碰撞的三维触发和kaons的三维fag镜相关性。 (3+1)D粘性流体动力学与Theminator 2代码进行统计强调。在所有三对方向上,获得的亲触发半径和kaons的tem镜射频是对横向动量和中心性的函数。随着所有中心的成对横向动量和横向质量的增加,半径显示出趋势下降。这些观察结果表明存在强大的集体性。对于锥形和kaons,观察到对半径的简单有效缩放。
The three-dimensional femtoscopic correlations of pions and kaons are presented for Pb$-$Pb collisions at \rootsNN = 5.02 TeV within the framework of (3+1)D viscous hydrodynamics combined with THERMINATOR 2 code for statistical hadronization. The femtoscopic radii for pions and kaons are obtained as a function of pair transverse momentum and centrality in all three pair directions. The radii showed a decreasing trend with an increase of pair transverse momentum and transverse mass for all centralities. These observations indicate the presence of strong collectivity. A simple effective scaling of radii with pair transverse mass was observed for both pion and kaons.
