摘要

对于重离子碰撞中高阶累积量的效率修正，我们提出了更简单的实验应用程序。通过使用逐迹效率，我们可以消除在相位空间的任意分组内计算的平均效率所产生的可能的偏差。此外，修正后的粒子谱不再用于平均效率估计，大大减少了计算自举统计误差的时间成本。

Efficiency correction for cumulants of multiplicity distributions based on track-by-track efficiency

We propose more simple procedures for the experimental application of the efficiency correction on higher order cumulants in heavy-ion collisions. By using the track-by-track efficiency, we can eliminate possible bias arising from the average efficiencies calculated within the arbitrary binning of the phase space. Furthermore, the corrected particle spectra is no longer necessary for the average efficiency estimation and the time cost for the calculation of bootstrap statistical error can be significantly reduced.
