A parametrization of the cosmic-ray muon flux at sea-level

TL;DR

This paper introduces a modified parametrization of the cosmic-ray muon flux at sea-level based on Gaisser's formula, verified against experimental data and used to simulate muon intensities at various depths.

Contribution

A new modified parametrization of the sea-level cosmic-ray muon flux is proposed and validated against experimental measurements.

Findings

The modified formula aligns well with experimental muon flux data.

Simulations using the modified formula match measured muon intensities at different depths.

The approach improves accuracy over previous models.

Abstract

Based on the standard Gaisser's formula, a modified parametrization for the sea-level cosmic-ray muon flux is introduced. The modification is verified against experimental results. The average vertical cosmic-ray muon intensity as a function of depth of standard rock is simulated using the modified formula as input to the MUSIC code. The calculated muon intensities is consistent with the experimental measurements.
