Bimaximal Mixing in an SO(10) Minimal Higgs Model [PDF]

open access: yes, 1999
An SO(10) SUSY GUT model was previously presented based on a minimal set of Higgs fields. The quark and lepton mass matrices derived fitted the data extremely well and led to large mixing of muon- and tau-neutrinos in agreement with the atmospheric ...

Solar Neutrino Measurements

open access: yes, 2018
We present the most recent results from the two currently running solar neutrino experiments, Borexino at the Gran Sasso laboratory in Italy and SuperK at Kamioka mine in Japan. SuperK has released the most precise yet measurement of the 8B solar neutrino interaction rate, with a precision better than 2\%, consistent with a constant solar neutrino ...

A Renormalizable Neutrino Mass Model With (Z2 × Z4)⋊Z2(II) Symmetry

open access: yesAdvances in High Energy Physics, Volume 2026, Issue 1, 2026.
In this work, a renormalizable neutrino mass model based on (Z2 × Z4)⋊Z2 (II) symmetry is proposed for the modification of the μ − τ reflection symmetry. The hierarchies of lepton masses can be naturally realized, and the lepton mixing is addressed.

Status and New Data of the Geochemical Determination of the pp-Neutrino Flux by LOREX

open access: yesAdvances in High Energy Physics, 2012
LOREX (LORandite EXperiment) addresses the determination of the solar (pp) neutrino flux during the last four million years by exploiting the reaction  205Tl+νe→ 205Pb+e- with an incomparably low-energy threshold of 50 keV for the capture of solar ...

The Super-Kamiokande experiment

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
Super-Kamiokande is a gigantic and versatile detector able to detect neutrinos with energies between a few MeV and a few hundred GeV. Super-K started data taking on 1st of April in 1996 after 5 years construction period and obtained compelling evidence ...

Quasi-sterile neutrinos from dark sectors. Part I. BSM matter effects in neutrino oscillations and the short-baseline anomalies.

open access: yesJournal of High Energy Physics, 2022
Quasi-sterile neutrinos are a natural consequence of dark sectors interacting with the Standard Model (SM) sector via neutrino- and vector-portals. Essentially, quasi-sterile neutrinos are light dark sector fermions with two generic properties: (i) they ...

Neutrino Masses and Mixing: Evidence and Implications [PDF]

open access: yes, 2002
Measurements of various features of the fluxes of atmospheric and solar neutrinos have provided evidence for neutrino oscillations and therefore for neutrino masses and mixing. We review the phenomenology of neutrino oscillations in vacuum and in matter.

Spectral Analysis of Flickering Gamma‐Ray Flashes Observed During the ALOFT 2023 Campaign

open access: yesJournal of Geophysical Research: Atmospheres, Volume 130, Issue 23, 16 December 2025.
Abstract We examine a newly discovered category of high‐energy radiation events called flickering gamma‐ray flashes (FGF) detected during the airborne lightning observatory for FEGS and TGFs campaign in July 2023. These FGFs are characterized by highly pulsating gamma‐ray emissions that have no detectable concurrent optical or radio signals (Ostgaard ...

Solar neutrinos and leptonic spin forces

open access: yesJournal of High Energy Physics
We quantify the effects of light spin-zero particles with pseudoscalar couplings to leptons and scalar couplings to nucleons on the evolution of solar neutrinos. In this scenario the matter potential sourced by the nucleons in the Sun’s matter gives rise

Direct detection of light dark matter and solar neutrinos via color center production in crystals

open access: yesPhysics Letters B, 2018
We propose a new low-threshold direct-detection concept for dark matter and for coherent nuclear scattering of solar neutrinos, based on the dissociation of atoms and subsequent creation of color center type defects within a lattice.
