| Abstract: |
Core-collapse supernovae are sources of tremendous numbers of neutrinos
with energies of tens of MeV. Detectors sensitive to these neutrinos, such as the proposed Deep Underground Neutrino Experiment (DUNE), present us with a number of exciting physics opportunities. Some of these include studies of neutrino oscillation physics over astronomical distances, probes of the early stages of stellar collapse, and an early warning system for incoming supernova light. To help enable supernova neutrino detection in next-generation liquid argon time projection chamber (LArTPC) experiments like DUNE, the CAPTAIN (Cryogenic Apparatus for Precision Tests of Argon Interactions with Neutrinos) collaboration plans to measure cross sections for neutrino interactions on argon in the supernova energy regime for the first time. In an effort to predict supernova neutrino event signatures in CAPTAIN and similar detectors, our group at UC Davis has been developing a first-of-its-kind Monte Carlo event generator called MARLEY (Model of Argon Reaction Low Energy Yields). This generator attempts to model low-energy neutrino-nucleus reactions in enough detail for use in LArTPC simulations. In this talk, we present an overview of the models being implemented in MARLEY, some preliminary simulation results, and our plans for continuing development of the code in the near future. |
