文摘

The NOMAD experiment includes a transition radiation detector that provides a 10³ pion rejection factor, for a 90 % electron identification efficiency. Such a rejection factor is required in the search for ν_μ → ν_τ oscillations in the τ electron decay channel and in the search for ν_μ → ν_e oscillations. Algorithms used for the electron-pion discrimination and results obtained on the data are described.
