Abstract

Results from the ν_τ appearance search in a neutrino beam using the full NOMAD data sample are reported. A new analysis unifies all the hadronic τ decays, significantly improving the overall sensitivity of the experiment to oscillations. The "blind analysis" of all topologies yields no evidence for an oscillation signal. In the two-family oscillation scenario, this sets a 90% CL allowed region in the sin²2θ_μτ-Δm² plane which includes sin²2θ_μτ<3.3×10^-4 at large Δm² and Δm²< 0.7 eV²/c⁴ at sin²2θ_μτ=1. The corresponding contour in the ν_e→ν_τ oscillation hypothesis results in sin²2θ_eτ<1.5×10^-2 at large Δm² and Δm²<5.9 eV²/c⁴ at sin²2θ_eτ=1. We also derive limits on effective couplings of the τ lepton to ν_μ or ν_e.

N2 - Results from the ντ appearance search in a neutrino beam using the full NOMAD data sample are reported. A new analysis unifies all the hadronic τ decays, significantly improving the overall sensitivity of the experiment to oscillations. The "blind analysis" of all topologies yields no evidence for an oscillation signal. In the two-family oscillation scenario, this sets a 90% CL allowed region in the sin22θμτ-Δm2 plane which includes sin22θμτ<3.3×10-4 at large Δm2 and Δm2< 0.7 eV2/c4 at sin22θμτ=1. The corresponding contour in the νe→ντ oscillation hypothesis results in sin22θeτ<1.5×10-2 at large Δm2 and Δm2<5.9 eV2/c4 at sin22θeτ=1. We also derive limits on effective couplings of the τ lepton to νμ or νe.
