Constraints on non-unitary neutrino mixing in light of atmospheric and reactor neutrino data

open access: yesJournal of High Energy Physics
While the origin of neutrino masses remains unknown, several key neutrino mass generation models result in a non-unitary three-neutrino mixing matrix. To put such models to test, the deviations of the mixing matrix from unitarity can be measured directly

Type II See-Saw Mechanism, Deviations from Bimaximal Neutrino Mixing and Leptogenesis

open access: yes, 2004
A possible interplay of both terms in the type II see-saw formula is illustrated by presenting a novel way to generate deviations from exact bimaximal neutrino mixing. In type II see-saw mechanism with dominance of the non-canonical SU(2)_L triplet term,

Optimizing nanofluid additives for enhanced thermophysical properties in anionic crude oil for EOR applications

open access: yesThe Canadian Journal of Chemical Engineering, Volume 102, Issue 7, Page 2418-2431, July 2024.
Abstract This research delved into the effects of introducing multi‐walled carbon nanotubes (MWCNTs) and sodium dodecyl sulphate (SDS) into crude oil with an anionic base, aiming to enhance its thermophysical attributes in the EOR process. The investigation encompassed a range of properties, including interfacial tension, viscosity, density, and ...

Leptogenesis in an SU(5)×A5 golden ratio flavour model

open access: yesNuclear Physics B, 2015
In this paper we discuss a minor modification of a previous SU(5)×A5 flavour model which exhibits at leading order golden ratio mixing and sum rules for the heavy and the light neutrino masses.

Radiative Corrections to Neutrino Mixing and CP Violation in the Minimal Seesaw Model with Leptogenesis

open access: yes, 2003
Radiative corrections to neutrino mixing and CP violation are analyzed in the minimal seesaw model with two heavy right-handed neutrinos. We find that textures of the effective Majorana neutrino mass matrix are essentially stable against renormalization ...

Democratic neutrino mixing reexamined

open access: yesPhysics Letters B, 2004
We reexamine the democratic neutrino mixing ansatz, in which the mass matrices of charged leptons and Majorana neutrinos arise respectively from the explicit breaking of S(3)_L x S(3)_R and S(3) flavor symmetries. It is shown that a democracy term in the neutrino sector can naturally allow the ansatz to fit the solar neutrino mixing angle _sun ...

Theory of neutrino slow flavor evolution. Part II. Space-time evolution of linear instabilities

open access: yesJournal of High Energy Physics
Slow flavor evolution (defined as driven by neutrino masses and not necessarily “slow”) is receiving fresh attention in the context of compact astrophysical environments.

The Increase in the Primordial He-4 Yield in the Two-Doublet Four-Neutrino Mixing Scheme

open access: yes, 2000
We assess the effects on Big Bang Nucleosynthesis (BBN) of lepton number generation in the early universe resulting from the two-doublet four-neutrino mass/mixing scheme. It has been argued that this neutrino mass/mixing arrangement gives the most viable

Deviations to Tri-Bi-Maximal mixing in the limit of μ − τ symmetry

open access: yesPhysics Letters B, 2019
In the limit of an approximate μ−τ symmetry in the neutrino mass matrix, we explore deviations to the Tri-Bi-Maximal mixing pattern in the neutrino sector.

The Ghent Hybrid model in NuWro: a new neutrino single-pion production model in the GeV regime

open access: yesJournal of High Energy Physics
Neutrino-induced single-pion production constitutes an essential interaction channel in modern neutrino oscillation experiments, with its products building up a significant fraction of the observable hadronic final states.
