The $\tau$-contamination of the golden muon sample at the Neutrino Factory

A. Donini, J. J. Gomez Cadenas, D. Meloni

We study the contribution of ${\nu }_e\to {\nu }_{\tau }\to \tau \to \mu$ transitions to the wrong-sign muon sample of the {\em golden} channel of the Neutrino Factory. Muons from tau decays are not re…
