Search for nu(mu)-->nu(e) Oscillations in the NOMAD Experiment
NOMAD Collaboration: P. Astier, et al
TL;DR
The NOMAD experiment searched for muon neutrino to electron neutrino oscillations and set new limits on oscillation parameters, excluding certain regions previously allowed by other experiments.
Contribution
This study provides the first comprehensive search for nu(mu) to nu(e) oscillations at CERN and establishes new constraints on oscillation parameters.
Findings
No evidence for nu(mu) to nu(e) oscillations was observed.
Set 90% confidence limits on oscillation parameters.
Excluded the LSND allowed region for delta m^2 > 10 eV^2.
Abstract
We present the results of a search for nu(mu)-->nu(e) oscillations in the NOMAD experiment at CERN. The experiment looked for the appearance of nu(e) in a predominantly nu(mu) wide-band neutrino beam at the CERN SPS. No evidence for oscillations was found. The 90% confidence limits obtained are delta m^2 < 0.4 eV^2 for maximal mixing and sin^2(2theta) < 1.4x10^{-3} for large delta m^2. This result excludes the LSND allowed region of oscillation parameters with delta m^2 > 10 eV^2.
