直接从重离子碰撞中测量的原始对计算球谐中的飞秒关联函数

Efficient and robust calculation of femtoscopic correlation functions in spherical harmonics directly from the raw pairs measured in heavy-ion collisions

Adam Kisiel, David A. Brown

摘要:

我们提出了直接用球谐函数计算飞秒关联函数的方法。分子和分母被存储为一组一维直方图,表示每个的球谐分解。我们提出的形式主义计算的关联函数直接从他们,而不去任何三维直方图。我们讨论的方法的实际实施,我们提供了一个例子,它的使用。我们还讨论了该方法的稳定性,在存在$θ$ - $ϕ$孔的基础数据(例如,从实验验收)。

英文摘要:

We present the formalism for calculating the femtoscopic correlation function directly in spherical harmonics. The numerator and denominator are stored as a set of one-dimensional histograms representing the spherical harmonic decompositions of each. We present the formalism to calculate the correlation function from them directly, without going to any three-dimensional histogram. We discuss the practical implementation of the method and we provide an example of its use. We also discuss the stability of the method in the presence of $θ$-$ϕ$ holes in the underlying data (e.g. from experimental acceptance).
