Title:     νPRISM: A new way of probing neutrino interactions

Abstract: In both neutrino interaction and neutrino oscillation measurements the rate of events you observe directly depends on the energy of the incident neutrino. Unfortunately this energy cannot be measured directly, and experiments instead rely on the outgoing lepton and any observed nucleons. To translate these observables into a neutrino energy we must assume knowledge of the neutrino interaction and average over the neutrino flux. Current measurements of neutrino-nucleon interactions do not agree well with existing models and indicate that the relationship between neutrino energy, true underlying interaction and particle kinematics is not well determined.

νPRISM is a proposed near detector for a long baseline neutrino beam experiment. Sited 1km from the beam production point, the detector spans a range of off-axis angles relative to the neutrino beam direction. As the off-axis angle changes so does the beam energy spectrum, providing a way of directly relating the neutrino energy to the experimental observables. This talk discusses the νPRISM concept, describing how it can be used for neutrino cross section measurements and showing how it reduces neutrino interaction uncertainties in oscillation measurements.


Please bring your own lunch.
