频率论置信水平导数的性质

Properties of frequentist confidence levels derivatives

Miriam Lucio Martínez, Diego Martínez Santos, Francesco Dettori

摘要:

在高能物理中,寻找新粒子或稀有过程的结果通常使用修改的频率论方法,称为$\rm{CL_s}$方法。在本文中,我们研究的$\rm{CL_s}$和$\rm{CL_{s+b}}$的衍生物的信号强度估计的性质,如果置信水平被解释为可信区间。我们的方法可以获得最佳拟合点和$χ^2$功能,可用于现象学研究。此外,该方法可用于将$\rm{CL_s}$结果合并到贝叶斯组合中。

英文摘要:

In high energy physics, results from searches for new particles or rare processes are often reported using a modified frequentist approach, known as $\rm{CL_s}$ method. In this paper, we study the properties of the derivatives of $\rm{CL_s}$ and $\rm{CL_{s+b}}$ as signal strength estimators if the confidence levels are interpreted as credible intervals. Our approach allows obtaining best fit points and $χ^2$ functions which can be used for phenomenology studies. In addition, this approach can be used to incorporate $\rm{CL_s}$ results into Bayesian combinations.
