使用概率事件加权从非干扰背景中分离信号

Separating Signals from Non-Interfering Backgrounds using Probabilistic Event Weightings

M. Williams, M. Bellis, C. A. Meyer

摘要:

在实验物理学中,一种常见的情况是,通过使用任何切割,都不能将信号从非干扰背景中分离出来。在本文中,我们描述了一个程序,用于确定,在一个事件的基础上,一个品质因数(Q因子),一个给定的事件起源于信号分布。然后,该Q因子可以在后续分析过程中用作事件权重,从而允许更直接地访问信号的真实频谱。

英文摘要:

A common situation in experimental physics is to have a signal which can not be separated from a non-interfering background through the use of any cut. In this paper, we describe a procedure for determining, on an event-by-event basis, a quality factor (Q-factor) that a given event originated from the signal distribution. This Q-factor can then be used as an event weight in subsequent analysis procedures, allowing one to more directly access the true spectrum of the signal.
