First Measurement of Monoenergetic Muon Neutrino Charged-Current Interactions
Abstract: The NuMI beam absorber provides an intense source of 236-MeV muon neutrino events originating from kaon decay at rest and is observable by the MiniBooNE detector, 86 meters away. The kaon decay at rest (KDAR) neutrino acts as a standard candle for studying neutrino-nucleus interactions, cross sections, and energy reconstruction in the hundreds of mega-electron-volt region and can be used for a number of precision measurements. The KDAR signal at MiniBooNE is distinguished from muon neutrino and anti-neutrino backgrounds by using arrival time and reconstructed muon energy. I will present the first measurement of neutrino-nucleus energy transfer using neutrinos and prospects for future measurements.
