Findings

Muon energy spectrum in the 10 TeV to 1 PeV range obtained.

Comparison with previous BUST data and models shows consistency.

Results contribute to understanding cosmic ray muon flux at high energies.

Abstract

Differential and integral energy spectra of cosmic ray muons in the energy range from several TeV to ~ 1 PeV obtained by means of the analysis of multiple interactions of muons (pair meter technique) in the Baksan underground scintillation telescope (BUST) are presented. The results are compared with preceding BUST data on muon energy spectrum based on electromagnetic cascade shower measurements and depth-intensity curve analysis, with calculations for different muon spectrum models, and also with data of other experiments.
