Progress toward a supernova neutrino event generator for simulations of liquid-argon-based detectors
Presented by Steven Gardiner, UC Davis
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.
