论文摘要
在[1]的附录中，我们将该论文中开发的技术应用于[2]中的$ J/ψ$和$购$旋转对准测量值。我们认为，尽管数据指向最大不纯的密度矩阵，这与Cooper-Frye/统计模型冻结一致，但测量了$ ϕ $敏感系数在相对于反应平面的方位角上的依赖性是对反应平面的重要测试。
In this addendum to [1], we apply the techniques developed in that paper to the $J/Ψ$ and $Υ$ spin alignement measurements in [2]. We argue that while the data points to a maximally impure density matrix, consistent with Cooper-Frye/Statistical model freeze-out, a measurement of the dependence of the $ϕ$-sensitive coefficients on the azimuthal angle with respect to the reaction plane would be the crucial test of this conclusion.
