“…Other proton beam-dump experiments which, besides LSND and MiniBooNE, can potentially exclude unexplored regions of the parameter space are SHiP, Coherent * (ORNL) [139] and SBN * (FNAL) [140]. All of them are multipurpose experiments with a wide neutrino research program.…”

The existence of Dark Matter (DM) is a well established fact since many decades, thanks to the observation of the effects of its gravitational interaction with the ordinary matter in the Universe. However, our knowledge of the Dark Matter features is still rather scarce. Indeed, one of the biggest quests in fundamental science today is the investigation of Dark Matter nature, from its origin to its composition, and the way its constituents interact with the ordinary matter, apart from gravity. Huge and ambitious efforts have been spent in the last years into its identification, concentrating especially on the search of viable Weakly Interacting Massive Particle candidates. However, no positive results have been achieved so far along this direction. On the other hand, many fascinating new ideas and models for its interpretation have been blooming: among them, an intriguing hypothesis is that the Dark Matter constituents could be neutral under Standard Model interactions, but they could interact through a new, still unknown, force under a "hidden" charge. This new hidden symmetry would be mediated by a massive gauge boson, the dark photon, which is expected to couple to the Standard Model via a kinetic mixing. The search for such a massive mediator has been pursued with large enthusiasm and dedication in the latest years, as its observation could be within the reach of many already existing experimental facilities, both based on accelerators or in smaller scale setups. This report reviews the present status and progress of the experimental searches in this field.

“…Finally, one could wonder what is the role of neutrino interaction uncertainties in this analysis. We will investigate that in detail in a forthcoming publication, but we would call the attention to the fact that the Short-Baseline Neutrino program [46] at Fermilab and DUNE will explore the sub-GeV region with high statistics. In fact, the DUNE-PRISM concept [47], a movable near detector to probe off-axis neutrinos, could greatly enhance our knowledge of neutrino-argon interactions at sub-GeV scales if the near detector hall allows for an off-axis distance of at least ∼ 25 meters.…”

Sub-GeV Atmospheric Neutrinos and CP Violation in DUNE

et al. 2019

We propose to use the unique event topology and reconstruction capabilities of liquid argon time projection chambers to study sub-GeV atmospheric neutrinos. The detection of low energy recoiled protons in DUNE allows for a determination of the leptonic CP -violating phase independent from the accelerator neutrino measurement. Our findings indicate that this analysis can exclude several values of δCP beyond the 3σ level. Moreover, the determination of the sub-GeV atmospheric neutrino flux will have important consequences in the detection of diffuse supernova neutrinos and in dark matter experiments.

“…In addition to the MicroBooNE, the two other detectors in Fermilab SBN program [16] using the Booster neutrino beam, ICARUS and ND using the same technology as MicroBooNE, are expected to take data in 2020 or 2021. Therefore, the long time mystery of the LSND result would be expected to be resolved soon.…”
