The Puzzle of Composition of Cosmic Rays with Energies (2–12.5) EeV According to Muon Detectors Data of the Yakutsk EAS Array

Year: 2025

Type: article

Abstract: The results of a study of the cosmic ray composition in individual events in the energy range (2–12.5) EeV using the muon correlation method [1] is presented. The considered sample included showers with zenith angles less than 60 degrees recorded in the period 1974–2018. The existence of four separate groups of primary particles with different origins is confirmed. The obtained results have potential importance for understanding the composition of cosmic rays in the specified primary energy range.
