Abstract

A method based on Bayes’ formula was used to estimate the relative error in determining the number of spectator nucleons from the energy measured in a calorimeter during the collision of relativistic nuclei. The minimum possible relative error in determining the number of spectator nucleons in an event is obtained for an arbitrary distribution of spectators.

根据量热计在 A + A 碰撞中测得的能量估算确定旁观核子数量的准确性

摘要使用了一种基于贝叶斯公式的方法来估算根据相对论原子核碰撞过程中在量热计中测得的能量来确定旁观者核子数的相对误差。对于任意的旁观者分布，得到了确定事件中旁观者核子数的最小可能相对误差。
