Matter Flavor Conversion Mediated by Pseudo-Sterile States as the Possible Origin of Neutrino Oscillation Anomalies
This research proposes a 3+1 neutrino model introducing a novel matter potential ($V_s$) for sterile neutrinos, linked to dark matter density. This framework resolves tensions in solar, long-baseline, and atmospheric neutrino experiments by modifying standard oscillation dynamics. It predicts specific resonant behaviors at different energy scales and provides constraints on mixing angles.
