Visible inelasticity in starting tracks can statistically separate tau and muon neutrino events, yielding competitive sensitivity to the tau-to-muon flux ratio with current IceCube exposures.
Little Red Dots can contribute ~30% of the diffuse neutrino background at TeV-sub-PeV energies through photomeson production in black hole envelopes, with modified flavor ratios at higher energies.
Correlated HNL discovery at SHiP and flavor ratio shifts in astrophysical neutrinos at telescopes would establish neutrinos as Majorana fermions.
Source-informed event selection in multi-level neutrino reconstruction improves median point source sensitivity by factors of ~2-3 over uniform subsampling.
High-energy astrophysical neutrinos can constrain the running of neutrino mixing parameters with energy, with future multi-detector setups forecast to set strong bounds despite astrophysical uncertainties.
PUEO will constrain the proton fraction of ultrahigh-energy cosmic rays under strong source evolution and set leading neutrino constraints on ultraheavy dark matter decays and some cosmic string models above 10^19 eV.
Constructs an effective Lindblad master equation for neutrino oscillations in Schwarzschild and Kerr spacetimes that incorporates curvature-enhanced decoherence and predicts flavor distortions and coherence loss observable by IceCube-Gen2, KM3NeT, and P-ONE.
The diffuse astrophysical neutrino flux is interpreted as dominated by a single source class with dominant pγ production for target photon temperatures of 0.1-1 keV.
With 5.4 Mt·year atmospheric neutrino exposure, ESSnuSB could constrain |ε_eμ^m| < 0.053, |ε_eτ^m| < 0.057, |ε_μτ^m| < 0.021 and related diagonal differences at 90% CL, while NSI would alter mass ordering and θ23 octant sensitivities.
Phenomenological study predicting incomplete tau polarization at FASER2, observable neutrino and muon trident processes, and contributions to hadron structure from IceCube neutrino events.
Correcting an omitted reality condition in the neutrino mass matrix elements allows the predicted neutrino mass sum to remain consistent with updated DESI and supernova data for both mass orderings.
