Final results on the search for ν μ →ν e oscillations in the NOMAD experiment

Abstract

The results of the search for ν μ →ν e oscillations in the NOMAD experiment at CERN are presented. The experiment looked for the appearance of ν e in a predominantly ν μ wideband neutrino beam at the CERN SPS. No evidence for oscillations was found. The 90% confidence limits obtained are Δm2<0.4 eV2 for maximal mixing and sin2(2θ)<1.4×10−3 for large Δm2. This result excludes the LSND allowed region of oscillation parameters with Δm2≳10 eV2.
