Abstract
The LSND experiment has observed a 3.8 sigma excess of ν̄e events from an ν̄μ beam coming from pions at rest. If confirmed, the LSND anomaly would imply new physics beyond the standard model. The MiniBooNE experiment shows a 1.6 σ disagreement with LSND results, but it introduces an unexplained, new 3.0 sigma anomaly at lower energies, down to 200 MeV.The proposal for a new eperiment based on two liquidArgon TPCs at CERN-PS is presented in this paper. The superior quality of the Liquid Argon imaging TPC and its unique electron – pi-zero discrimination allow full rejection of the NC background, without efficiency loss for electron neutrino detection. The use of two detectors at a near and a far location enables to minimize the effects of systematic uncertainties related to the neutrino beam and to the neutrino cross-sections. This experiment could collect 106 charged current events in two years data taking, thus allowing for a high priecision and high statistics study of the LSND and MiniBoone anomalies
