NUFACT'03: The Fate of the Clones

Abstract

We present a Neutrino-Factory-based setup with three detectors of different kind in principle capable to solve the eightfold-degeneracy in the simultaneous measurement of $\theta_{13}$ and $\delta$, for $\theta_{13} \geq 1^\circ (\sin^2 (2 \theta_{13}) \geq 10^{-3})$. Our setup includes a Superbeam-driven water Cherenkov (the Superbeam conceived as the first stage of the Neutrino Factory); two muon-storage-ring-driven detectors (namely, a large magnetized iron calorimeter and an emulsion cloud chamber) to take advantage of both the so-called "golden" ($\nu_e \to \nu_\mu$) and "silver" ($\nu_e \to \nu_\tau$) channels.
