Precise determination of the oscillation parameters: need to understand low energy neutrino interactions

Precise measurements of the neutrino oscillation parameters will be an important part of the experimental program of high energy physics in the years to come. High intensity conventional beams and/or neutrino factories will be necessary to attain the ultimate precision. Measurements of the oscillation parameters performed at low neutrino energies, below 10 GeV, may suffer for systematic uncertainties caused by relatively poor knowledge of neutrino physics at low energies and by nuclear effects. Dedicated new experiments are necessary to constrain modeling of neutrino interactions necessary for the precise fit of the oscillation parameters
