High Energy Cosmic Tau Neutrinos

TL;DR

This paper explores the production, propagation, and detection prospects of high energy cosmic tau neutrinos (above 10^6 GeV), emphasizing the effects of neutrino mixing and potential observation methods in large-scale neutrino telescopes.

Contribution

It introduces the study of high energy cosmic tau neutrinos, focusing on their production mechanisms, mixing effects during propagation, and detection strategies in large neutrino observatories.

Findings

High energy tau neutrinos can be produced in astrophysical sites.

Neutrino mixing significantly affects tau neutrino propagation.

Double shower events are promising for detecting these neutrinos.

Abstract

I discuss the possibility of production of high energy cosmic tau neutrinos ($E \geq 10^{6}$ GeV) in an astrophysical site and study some of the effects of neutrino mixing on their subsequent propagation. I also discuss the prospects for observations of these high energy cosmic tau neutrinos through double shower events in new km$^{2}$ surface area under water/ice neutrino telescopes.
