Abstract

Seasonal variations of atmospheric muons are traditionally interpreted in terms of an effective temperature that relates the atmospheric temperature profile at a given time to the dependence of muon production on atmospheric depth. This paper aims to review and generalize the treatment of muon production and effective temperature that has been used to interpret seasonal variations of atmospheric muons by many experiments. The formalism is developed both in integral form – for application to compact detectors at a fixed depth that record all muons with Eμ>Eμmin – and in differential form — for application to extended detectors like IceCube, KM3NeT, and Baikal-GVD, where the rates are proportional to energy-dependent effective areas.

大气渺子及其随温度的变化
大气μ介子的季节性变化传统上是用有效温度来解释的,它将给定时间的大气温度剖面与μ介子产生量对大气深度的依赖性联系起来。本文旨在回顾和归纳μ介子产生和有效温度的处理方法,许多实验都使用这种方法来解释大气μ介子的季节性变化。形式主义是以积分形式和微分形式发展的,前者适用于在固定深度记录所有具有 Eμ>Eμmin 的μ介子的紧凑型探测器,后者适用于冰立方、KM3NeT 和贝加尔-GVD 等扩展型探测器,在这些探测器中,μ介子的产生率与能量相关的有效面积成正比。
