在未知非单调背景下寻找质量和寿命未知的粒子
Searching for a particle of unknown mass and lifetime in the presence of an unknown non-monotonic background
摘要：
粒子物理学标准模型的许多扩展都假设存在新的低质量粒子。通常，对这种粒子的质量或寿命几乎没有理论约束。这就要求实验者在粒子的质量和寿命都未知的情况下进行搜索。这种对低质量粒子的搜索由于可能存在共振和其他非单调背景而变得复杂。本文提出了一种简单而快速的方法来分配的意义和设置限制，在这样的搜索。
英文摘要：
Many extensions to the Standard Model of particle physics hypothesize the existence of new low-mass particles. Typically there are few theoretical constraints on the mass or lifetime of such particles. This requires the experimentalist to perform a search in which both the mass and lifetime of the particle are unknown. Such searches for low-mass particles are complicated by the possible presence of resonances and other non-monotonic backgrounds. This paper presents a simple and fast approach to assigning significance and setting limits in such searches.
