Gravitational interactions and neutrino masses [PDF]

Physical Review D, 2020
We describe a scenario where the smallness of neutrino masses is related to a global symmetry that is only violated by quantum gravitational effects. The coupling of neutrinos to gauge singlet right-handed fermions is attributed to symmetry preserving gravitational operators suppressed by the Planck mass, in this framework.

Quasielastic neutrino-nucleus interactions [PDF]

Nuclear Physics B, 1971
Abstract Calculations of the Pauli exclusion effect are made in a simple shell model. Shell structure effects, associated with spin-orbit splitting, appear, but are not large and decrease rapidly with increasing momentum transfer. The shell model remains less exclusive on the whole than the standard Fermi gas, but not sufficiently so to explain the ...

Work Versus Force: Simultaneous Processes for Describing Interactions

Advanced Physics Research, Volume 5, Issue 6, June 2026.
ABSTRACT Achieving a unified description of interactions remains an open challenge in theoretical physics, which currently describes four fundamental forces. This situation may be viewed differently when interactions are formulated in terms of processes (work as actio) rather than forces (force as actio), not only at the macroscopic level but also at ...

Enhancing the sensitivity to neutrino oscillation parameters using synergy between T2K, NOνA and JUNO

Journal of High Energy Physics
We study the impact of combining the present NOνA and T2K data with simulated data from the JUNO experiment on the determination of the leptonic CP phase and the neutrino mass hierarchy.

Hidden No More: Spotlight on Tidal Disruption Events in Active Galactic Nuclei

Astronomische Nachrichten, Volume 347, Issue 5, June 2026.
ABSTRACT Tidal disruption events (TDEs) are typically discovered in previously quiescent galaxies. However, earlier studies have revealed a handful of TDEs occurring in pre‐existing active galactic nuclei (AGN). We discuss AT2019aalc, a promising TDE candidate in an AGN, and compare it to similar sources.

Dispersion relation of the neutrino plasma: unifying fast, slow, and collisional instabilities

Journal of High Energy Physics
In neutrino-dense astrophysical environments, these particles exchange flavor through a coherent weak field, forming a collisionless neutrino plasma with collective flavor dynamics.

Methods to estimate marine functional connectivity: A primer

Ecological Applications, Volume 36, Issue 4, June 2026.
Abstract Organism movement is a key process in the transfer of individuals, genes, functional traits, matter, and energy among habitat patches, at sea and across the land–sea interface. The resulting fluxes, collectively termed marine functional connectivity (MFC), underpin planetary health and an array of ecosystem services.

Single-wave solutions of the neutrino fast flavor system. Part I. Mechanical properties

Journal of High Energy Physics
A dense neutrino plasma can exhibit collective flavor evolution caused by neutrino-neutrino refraction. Recently, a new class of exact nonlinear inhomogeneous solutions was discovered: single-wave (SW) solutions of the fast flavor system.

Nonstandard interactions in solar neutrino oscillations with Hyper-Kamiokande and JUNO

Physics Letters B, 2017
Measurements of the solar neutrino mass-squared difference from KamLAND and solar neutrino data are somewhat discrepant, perhaps due to nonstandard neutrino interactions in matter.

Microscopic and macroscopic effects in the decoherence of neutrino oscillations

Journal of High Energy Physics, 2022
We present a generic structure (the layer structure) for decoherence effects in neutrino oscillations, which includes decoherence from quantum mechanical and classical uncertainties. The calculation is done by combining the concept of open quantum system
