Detector Depth Dependence of the High Energy Atmospheric Neutrino Flux

TL;DR

This paper discusses how the depth of neutrino detectors affects the atmospheric neutrino flux due to variations in decay path lengths, leading to potential location-dependent flux modulations.

Contribution

It highlights the significance of detector depth in atmospheric neutrino flux calculations and quantifies the potential flux variation based on location.

Findings

Detector depth influences decay path lengths of particles producing neutrinos.

Neutrino flux modulation can reach 5-10% depending on location.

Location-dependent effects are significant for neutrino observations.

Abstract

We note that detector depth can influence the decay path length available for the primary and secondary particles that are the source of atmospheric neutrinos. As a consequence there is a location dependent modulation to the neutrino flux, which could be as large as 5-10% in some directions.
