I worked with @PedroANMachado and Roni Harnik on the idea of using neutrinos that come from a ""decay-at-rest"" process to measure neutrino oscillations. <LINK> @PedroANMachado When we try to understand neutrino oscillations, knowing how far they've travelled and how much energy they have is crucial for interpreting a result. Decay-at-rest neutrinos are special in that certain types can only have one energy. <LINK> @PedroANMachado If we can measure them after travelling hundreds of kilometers, then we can start to pinpoint how neutrinos oscillate over many different lengths and energies, and start to stress-test our theories of neutrino oscillations. @PedroANMachado In the next decade, the J-PARC Spallation Neutron Source and the Hyper-Kamiokande experiment are a great opportunity for this type of measurement -- we can start to add stars to that panel and really hone in on neutrino oscillations.",https://arxiv.org/abs/1911.05088,"In addition to the next generation of beam-based neutrino experiments and their associated detectors, a number of intense, low-energy neutrino production sources from decays at rest will be in operation. In this work, we explore the physics opportunities with decay-at-rest neutrinos for complementary measurements of oscillation parameters at long baselines. The J-PARC Spallation Neutron Source, for example, will generate neutrinos from a variety of decay-at-rest (DAR) processes, specifically those of pions, muons, and kaons. Other proposed sources will produce large numbers of stopped pions and muons. We demonstrate the ability of the upcoming Hyper-Kamiokande experiment to detect the monochromatic kaon decay-at-rest neutrinos from J-PARC after they have travelled several hundred kilometers and undergone oscillations. This measurement will serve as a valuable cross-check in constraining our understanding of neutrino oscillations in a new regime of neutrino energy and baseline length. We also study the expected event rates from pion and muon DAR neutrinos in liquid Argon and water detectors and their sensitivities to to the CP violating phase $\delta_\mathrm{CP}$.
