A novel concept for the detection of tau neutrino appearance

TL;DR

This paper introduces a new method for detecting tau neutrinos by imaging Cherenkov light from tau leptons in a liquid, showing promising simulation results for identifying about half of the tau leptons produced.

Contribution

It presents a novel detection concept for tau neutrinos using Cherenkov light imaging, suitable for long-baseline neutrino experiments.

Findings

Approximately 50% of tau leptons can be identified using the proposed method.

The detection approach is based on direct imaging of Cherenkov light in liquid.

The concept is supported by simple simulation results.

Abstract

A novel concept for the detection of tau neutrinos is presented, potentially suitable for use in a long-baseline neutrino oscillation experiment. It relies on the direct identification of the tau leptons produced in charged-current interactions, by imaging the Cherenkov light that the tau generates in C6F14 liquid. In a simple simulation about half of the tau leptons can be successfully identified in this way.
