Abstract :
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 νμ→ντ oscillations in the τ electron decay channel and in the search for νμ→νe oscillations. Algorithms used for the electron–pion discrimination and results obtained on the data are described.
