“…The presence of these gamma rays would strongly favor that an event is due to ν e + 40 Ar. For ν e,µ,τ + e − events, gamma rays can be produced through bremsstrahlung, but that is suppressed because the event energies are well below the critical energy of 32 MeV [45][46][47]. And for neu- tron capture, the total energy release is 6.1 MeV, with at most one gamma ray having substantial energy [72][73][74].…”

“…Above 5 MeV, electrons are expected to be detected with high efficiency and 7% energyindependent energy resolution [27]. For solar signals, electrons lose energy dominantly by ionization, as the critical energy of LAr is 32 MeV [45][46][47]. The angular resolution of DUNE is uncertain, so we adopt simulation results for ICARUS [29], with a smearing of ∼ 25 • .…”

DUNE as the Next-Generation Solar Neutrino Experiment

et al. 2019

We show that the Deep Underground Neutrino Experiment (DUNE) has the potential to deliver world-leading results in solar neutrinos. Significant but realistic new efforts would be required. With an exposure of 100 kton-year, DUNE could detect 10 5 signal events above 5 MeV. Separate precision measurements of neutrino-mixing parameters and the 8 B flux could be made using two detection channels (νe + 40 Ar and νe,µ,τ + e − ) and the day-night effect (> 10σ). New particle physics may be revealed through the comparison of solar neutrinos (with matter effects) and reactor neutrinos (without), which is discrepant by ∼ 2σ (and could become 5.6σ). New astrophysics may be revealed through the most precise measurement of the 8 B flux (to 2.5%) and the first detection of the hep flux (to 11%). DUNE is required: No other experiment, even proposed, has been shown capable of fully realizing these discovery opportunities.12 θ 2 sin 0.2 0.3 0.4

LSND/MiniBooNe excess events and heavy neutrino fromμandKdecays

It has been recently shown that puzzling excess events observed by the LSND and MiniBooNE neutrino experiments could be interpreted as a signal from the radiative decay of a heavy sterile neutrino ( h ) of the mass from 40 to 80 MeV, with a muonic mixing strength jU h j 2 ' 10 À3 -10 À2 , and the lifetime 10 À11 & h & 10 À9 s. We discuss bounds on jU h j 2 obtained from the recent precision measurements with muons and show that they are consistent with the above limits. If the h exists its admixture in the ordinary muon or kaon decay would result in the decay chain ! e e h ! e e or K ! h ! , respectively. We propose a new experiment for a sensitive search for these processes in and K decays at rest allowing to either definitively confirm or exclude the existence of the h . To our knowledge, no experiment has specifically searched for the signature of radiative decay of massive neutrinos from particle decays as proposed in this work. The search is complementary to the current experimental efforts to clarify the origin of the LSND and MiniBooNE anomalies.

“…In most of the existing measurements, LArTPCs were placed in high energy neutrino beams to study GeV-scale muon and electron neutrinos as well as final-state products, generally with energies greater than 100 MeV. A smaller number of measurements have investigated particles or energy depositions in the < 100 MeV range [6,15,16], some using scintillation light [17].…”

Demonstration of MeV-scale physics in liquid argon time projection chambers using ArgoNeuT

MeV-scale energy depositions by low-energy photons produced in neutrino-argon interactions have been identified and reconstructed in ArgoNeuT liquid argon time projection chamber (LArTPC) data. ArgoNeuT data collected on the NuMI beam at Fermilab were analyzed to select isolated low-energy depositions in the TPC volume. The total number, reconstructed energies and positions of these depositions have been compared to those from simulations of neutrino-argon interactions using the FLUKA Monte Carlo generator. Measured features are consistent with energy depositions from photons produced by de-excitation of the neutrino's target nucleus and by inelastic scattering of primary neutrons produced by neutrino-argon interactions. This study represents a successful reconstruction of physics at the MeV-scale in a LArTPC, a capability of crucial importance for detection and reconstruction of supernova and solar neutrino interactions in future large LArTPCs. *
