“…Our findings highlight the importance of running the full SBN program, and of complementing it with the worldwide efforts to search for light sterile neutrinos in reactor [66][67][68][69][70], radioactive source [49], accelerator [71][72][73][74], solar [54,75], and atmospheric neutrino [63,[76][77][78][79][80] experiments. Together, these experiments will have sufficient sensitivity to answer this decades-old puzzle once and for all.…”

A new generation of neutrino experiments is testing the 4.7σ anomalous excess of electronlike events observed in MiniBooNE. This is of huge importance for particle physics, astrophysics, and cosmology, not only because of the potential discovery of physics beyond the standard model, but also because the lessons we will learn about neutrino-nucleus interactions will be crucial for the worldwide neutrino program. MicroBooNE has recently released results that appear to disfavor several explanations of the MiniBooNE anomaly. Here, we show quantitatively that MicroBooNE results, while a promising start, unquestionably do not probe the full parameter space of sterile neutrino models hinted at by MiniBooNE and other data, nor do they probe the ν e interpretation of the MiniBooNE excess in a model-independent way.

Proposed experiments such as IsoDAR@Yemilab [137,138] will be rid of large systematic flux uncertainties, and will be able to reconstruct the antineutrino's energy and propagated distance with high precision on an event-by-event basis. As such, it should be able to resolve the ambiguities and inconsistencies that currently plague the ν ( ) e disappearance experimental landscape.…”

Quasi-sterile neutrinos are a natural consequence of dark sectors interacting with the Standard Model (SM) sector via neutrino-and vector-portals. Essentially, quasisterile neutrinos are light dark sector fermions with two generic properties: (i) they mix with the active neutrinos of the SM, and (ii) they are charged under a vector mediator that couples feebly to SM matter. Various interesting phenomenological consequences result from this class of particles. In this article, we investigate one such consequence: new, beyond the SM matter effects that can alter in-medium neutrino oscillations. In particular, for special windows of energy and matter densities, active neutrinos can resonantly oscillate into sterile neutrinos. We take advantage of this feature to build a quasi-sterile neutrino model that can explain the MiniBooNE and LSND anomalies, while remaining compatible with observations from long-baseline reactor-and accelerator-based neutrino experiments. This model is also likely compatible with the recent results reported by the MicroBooNE collaboration (albeit we cannot precisely quantify this claim due to a lack of information in MicroBooNE's public data releases to date). Implications for solar neutrinos and ν e disappearance searches are also briefly discussed.
