A medium baseline search for $ν_μ\toν_e$ oscillations at a $ν$ beam from muon decays

Abstract

The accurate knowledge of the $\barν_e (ν_μ)$ beam produced in $μ^-$ decays and the absence of $ν_e (\barν_μ)$ 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 $μ$-collider, the LSND claim would be confirmed or disproved in a few years of running.
