On the Mechanism of Temperature Variations in the Average Energy of Muons at Large Depths

TL;DR

This paper investigates how seasonal temperature changes affect the average energy of muons detected deep underground, attributing variations to atmospheric muon production and rock passage effects.

Contribution

It provides a detailed analysis of the mechanisms causing temperature-related energy variations of muons at large depths, linking atmospheric and geological factors.

Findings

Temperature variations influence muon energy at large depths.

Muon generation in the atmosphere affects underground muon energy.

Rock passage modifies muon energy depending on atmospheric conditions.

Abstract

Sources of seasonal temperature variations in the average energy of the muon flux detected in the LVD experiment have been discussed. It has been shown that variations are due to the processes of generation of muons in upper layers of the atmosphere and the passage of muons through a thick rock layer.
