In the practical calculation, after producing in solar core, 3 we adopt adiabatic approximation to describe neutrino propagation through other part of the sun and the vacuum between sun and the Earth. For the Earth model, we take the slab JHEP09(2022)029 approximation to describe the terrestrial matter [52].…”

“…The LSND anomaly is the 3.8σ excess of events compatible to νe appearance in a νµ beam observed by the LSND experiment [1], while the MiniBooNE anomaly is the 4.8σ excess of electron-like events in the MiniBooNE experiment observed in both ν µ and νµ beams [2]. As a direct test of LSND anomaly, the JSNS 2 experiment has started data taking [3] at J-PARC in Japan. With the same neutrino beam as MiniBooNE but superior event reconstruction capabilities, the MicroBooNE collaboration recently has released results scrutinizing the MiniBooNE anomaly, known as the MiniBooNE low-energy excess (MBLEE).…”

The renormalization-group equation (RGE) approach to neutrino matter effects is further developed in this work. We derive a complete set of differential equations for effective mixing elements, masses and Jarlskog-like invariants in presence of a light sterile neutrino. The evolutions of mixing elements as well as Jarlskog-like invariants are obtained by numerically solving these differential equations. We calculate terrestrial matter effects in long-baseline (LBL) experiments, taking NOvA, T2K and DUNE as examples. In both three-flavor and four-flavor frameworks, electron-neutrino survival probabilities as well as the day-night asymmetry of solar neutrino are also evaluated as a further examination of the RGE approach.

The upcoming European Spallation Source (ESS) will soon provide the most intense neutrino source in the world. We propose the Search for Hidden Neutrinos at the ESS (SHiNESS) experiment, highlighting its unique opportunities to search for the existence of sterile neutrinos across a wide range of scales: anomalous oscillations at short baselines; non-unitarity mixing in the active neutrino sector; or an excess of events with multiple leptons in the final state, produced in the decay of heavy neutrinos. The baseline design of the detector comprises an active volume filled with 42 ton of liquid scintillator, located 25 m far from the ESS beam target. We show that SHiNESS will be able to considerably improve current global limits for the three cases outlined above. Although in this work we focus on new physics in the neutrino sector, the proposed setup may also be used to search for signals from weakly interacting particles in a broader context.
