Neutrino-4 anomaly: Oscillations or fluctuations?

open access: yesPhysics Letters B, 2021
We present a deep study of the Neutrino-4 data aimed at finding the statistical significance of the large-mixing short-baseline neutrino oscillation signal claimed by the Neutrino-4 collaboration at more than 3σ. We found that the results of the Neutrino-

Massless neutrino oscillations [PDF]

open access: yesPhysical Review D, 2001
Quantum dynamical semigroups provide a general framework for studying the evolution of open systems. Neutrino propagation both in vacuum and in matter can be analyzed using these techniques: they allow a consistent treatment of non-standard, dissipative effects that can alter the pattern of neutrino oscillations.

Superluminal velocity through near-maximal neutrino oscillations or by being off shell

open access: yes, 2012
Recently it was suggested that the observation of superluminal neutrinos by the OPERA collaboration may be due to group velocity effects resulting from close-to-maximal oscillation between neutrino mass eigenstates, in analogy to known effects in optics.

Extrinsic CPT Violation in Neutrino Oscillations [PDF]

open access: yes, 2004
In this talk, we investigate extrinsic CPT violation in neutrino oscillations in matter with three flavors. Note that extrinsic CPT violation is different from intrinsic CPT violation.

Gravitational Radiation From Binary Systems With Time Varying Masses

open access: yesAnnalen der Physik, Volume 538, Issue 8, August 2026.
We extend the standard approach pioneered in the works by Peters and Mathews to include the mass loss processes of the binary components, by obtaining the variations due to gravitational radiation of the main physical parameters. As an application of our results we consider gravitational radiation emission in binary magnetar systems.

Testing νMSM with indirect searches

open access: yesPhysics Letters B, 2015
We consider neutrino Minimal extension of the Standard Model (νMSM), which by introducing only three sterile neutrinos in sub-electroweak region can explain active neutrino oscillations (via seesaw type-I mechanism), baryon asymmetry of the Universe ...

Polychromatic Population of Bioluminescent Organisms in the Deep Pacific Ocean

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 7, July 2026.
Abstract We present a comprehensive study of deep‐sea bioluminescent organisms in the Cascadia Basin, Northeast Pacific Ocean, based on four years (2020–2023) of in situ measurements using STRings for Absorption length in Water instruments. Analysis of over 1.3 million camera images and continuous photomultiplier tube recordings revealed that ...

A short travel for neutrinos in Large Extra Dimensions

open access: yesJournal of High Energy Physics, 2018
Neutrino oscillations successfully explain the flavor transitions observed in neutrinos produced in natural sources like the center of the sun and the earth atmosphere, and also from man-made sources like reactors and accelerators. These oscillations are

Neutrino flavor relaxation or neutrino oscillations? [PDF]

open access: yesJournal of Experimental and Theoretical Physics Letters, 2004
We propose the new mechanism of neutrino flavour relaxation to explain the experimentally observed changes of initial neutrino flavour fluxes. The test of neutrino relaxation hypothesis is presented, using the data of modern reactor, solar and accelerator experiments. The final choice between the standard neutrino oscillations and the proposed neutrino

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

open access: yesAstronomische 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.
