“…Possible paths toward a full open-source simulation include modifying the default behavior of the GENIE interface to the Geant4 Bertini cascade (as mentioned in [79]), combining the MARLEY deexcitation simulation with the intranuclear cascade of one of the high-energy generators, and creating an interface between an existing neutrino event generator and a low-energy nuclear reaction code. The last of these options has recently been pursued unofficially [100,101] for GENIE and NuWro using TALYS [102].…”

In this paper, we review scientific opportunities and challenges related to detection and reconstruction of low-energy (less than 100 MeV) signatures in liquid argon time-projection chamber (LArTPC) neutrino detectors. LArTPC neutrino detectors designed for performing precise long-baseline oscillation measurements with GeV-scale accelerator neutrino beams also have unique sensitivity to a range of physics and astrophysics signatures via detection of event features at and below the few tens of MeV range. In addition, low-energy signatures are an integral part of GeV-scale accelerator neutrino interaction final-states, and their reconstruction can enhance the oscillation physics sensitivities of LArTPC experiments. New physics signals from accelerator and natural sources also generate diverse signatures in the low-energy range, and reconstruction of these signatures can increase the breadth of Beyond the Standard Model scenarios accessible in LArTPC-based searches. A variety of experimental and theory-related challenges remain to realizing this full range of potential benefits. Neutrino interaction cross-sections and other nuclear physics processes in argon relevant to sub-hundred-MeV LArTPC signatures are poorly understood, and improved theory and experimental measurements are needed; pion decay-at-rest sources and charged particle and neutron test beams are ideal facilities for improving this understanding. There are specific calibration needs in the low-energy range, as well as specific needs for control and understanding of radiological and cosmogenic backgrounds. Low-energy signatures, whether steady-state or part of a supernova burst or larger GeV-scale event topology, have specific triggering, DAQ and reconstruction requirements that must be addressed outside the scope of conventional GeV-scale data collection and analysis pathways. Novel concepts for future LArTPC technology that enhance low-energy capabilities should also be explored to help address these challenges.

“…First, the nuclear shell structure is considered, which is not included in the default nuclear model of GENIE. A spectral function model, which provides a two-dimensional distribution of momentum k and the removal energy for protons in , is applied to describe the initial proton states [23]. Then, the initial proton energy is determined by , where is the mass of a free proton.…”

The Jiangmen Underground Neutrino Observatory (JUNO) is a large liquid scintillator detector designed to explore many topics in fundamental physics. In this paper, the potential on searching for proton decay in p → ν K+ mode with JUNO is investigated. The kaon and its decay particles feature a clear three-fold coincidence signature that results in a high efficiency for identification. Moreover, the excellent energy resolution of JUNO permits to suppress the sizable background caused by other delayed signals. Based on these advantages, the detection efficiency for the proton decay via p → ν K+ is 36.9%±4.9% with a background level of 0.2±0.05(syst)±0.2(stat) events after 10 years of data taking. The estimated sensitivity based on 200 kton-years exposure is 9.6 × 1033 years, which is competitive with the current best limits on the proton lifetime in this channel and complementary using different detection technologies.
