搜索新信号的灵敏度及其优化
Sensitivity of searches for new signals and its optimization
摘要：
讨论了寻找新现象的灵敏度的频率论定义，它具有几个有用的性质。它是基于完全标准的概念，是普遍适用的，并有一个非常明确的解释。它特别适合于优化，独立于关于信号存在的先验期望，从而允许确定对于设定限制和进行发现都是最佳的单组切割。对于有背景的泊松计数这一常见问题，给出了简单的近似公式。
英文摘要：
A frequentist definition of sensitivity of a search for new phenomena is discussed, that has several useful properties. It is based on completely standard concepts, is generally applicable, and has a very clear interpretation. It is particularly suitable for optimization, being independent of a-priori expectations about the presence of a signal, thus allowing the determination of a single set of cuts that is optimal both for setting limits and for making a discovery. Simple approximate formulas are given for the common problem of Poisson counts with background.
