A medium baseline search for ${\nu }_{\mu }\to {\nu }_e$ oscillations at a $\nu$ beam from muon decays

Abstract

The accurate knowledge of the ${\bar{\nu }}_e({\nu }_{\mu })$ beam produced in ${\mu }^{-}$ decays and the absence of ${\nu }_e({\bar{\nu }}_{\mu })$ contamination, make a future muon storage ring the ideal place to look for $\numunue$ ($\numubarnuebar$) oscillations. Using a detector capable of electron and muon identification with charge discrimination (e.g., the presently running NOMAD experiment), good sensitivities to $\numunue (\numubarnuebar)$ oscillations could be achieved. With the CERN-PS as a proton driver for a muon storage ring of the kind envisaged for a $\mu$-collider, the LSND claim would be confirmed or disproved in a few years of running.
