Four-neutrino oscillations [PDF]

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2000
It is shown that at least four massive neutrinos are needed in order to accommodate the evidences in favor of neutrino oscillations found in solar and atmospheric neutrino experiments and in the LSND experiment. Among all four-neutrino schemes, only two, with a mass spectrum composed of two pairs of neutrinos with close masses separated by the "LSND ...

Toward Large Nonradiating Qubits: When Quantum Engineering Meets Photonics

Advanced Quantum Technologies, Volume 9, Issue 3, March 2026.
Nonradiating superconducting qubits suppress radiative losses through photonic‐inspired mechanisms such as anapole states and bound states in the continuum (BICs). This review surveys theoretical foundations and recent implementations of large, wavelength‐scale qubits that confine electromagnetic energy while maintaining coherence.

Testing νMSM with indirect searches

Physics 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 ...

Neutrino flavor relaxation or neutrino oscillations? [PDF]

Journal 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

A New Method for Probabilistic Spatiotemporal Forecasts of Solar Soft X‐Ray “S‐Class” (>X10) Superflares

Journal of Geophysical Research: Space Physics, Volume 131, Issue 2, February 2026.
Abstract Solar superflares of S‐class (>X10 in soft X‐rays) pose extreme space weather hazards, yet their prediction remains a fundamental challenge owing to their rapid and transient natures and the limitations of conventional event‐based forecasts. We introduce for the first time, a probabilistic spatiotemporal framework designed to identify extended

A short travel for neutrinos in Large Extra Dimensions

Journal 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

Coherence and mixedness of neutrino oscillations in a magnetic field

European Physical Journal C: Particles and Fields, 2021
The radical departure from classical physics implies quantum coherence, i.e., coherent superposition of eigenstates of Hermitian operators. In resource theory, quantum coherence is a resource for quantum operations.

Limits on $\nu_{\mu}(\nu_{e}) \to \nu_{\tau}$ oscillations and tau neutrino magnetic moment from neutrino-electron scattering

, 1997
The combined effect of neutrino flavor oscillations and neutrino magnetic moment on neutrino-electron scattering is discussed. It is shown, that if the tau neutrino has a (large) magnetic moment and can oscillate into a neutrino of another flavor it can ...

Whipped and Mixed Warm Clouds in the Deep Sea

Geophysical Research Letters, Volume 53, Issue 2, 28 January 2026.
Abstract Turbulence is indispensable to redistribute nutrients for all life forms larger than microbial, on land and in the ocean. Yet, the development of deep‐sea turbulence was not studied in three dimensions to date. As a disproportionate laboratory, an array of nearly 3,000 high‐resolution temperature sensors had been installed for three years on ...

Off-diagonal structure of neutrino mass matrix in see-saw mechanism and electron-muon-tau lepton universality

, 2000
By a simple extension of the standard model in which ($e-\mu -\tau $) universality is not conserved, we present a scenario within the framework of see-saw mechanism in which the neutrino mass matrix is strictly off-diagonal in the flavor basis.
