Status of the Search for nu-mu to nu-tau Oscillations with the CHORUS Detector

TL;DR

The CHORUS experiment investigates muon neutrino to tau neutrino oscillations using emulsion and electronic detectors, aiming to improve sensitivity to small mixing angles for neutrino mass differences over 10 eV^2.

Contribution

This work reports on the status and capabilities of the CHORUS experiment to detect neutrino oscillations with enhanced sensitivity compared to previous experiments.

Findings

Two years of data collection completed

Expected to improve limits on neutrino mixing angles

Probing mass differences > 10 eV^2

Abstract

The CHORUS experiment is searching for nu-mu to nu-tau oscillations using an 800 kilogram emulsion target and an electronic detector. Two of four years of running have been completed. The experiment will probe small mixing angles for squared neutrino mass differences greater than 10 eV^2, at least one order of magnitude better than previous limits.
