Neutrino mixing: A4 variations
Physics Letters B, 2016 In the context of the non-Abelian discrete symmetry $A_4$, the neutrino mass matrix has been studied extensively. A brief update is presented to focus on the conceptual shift from tribimaximal mixing ($ _{13} = 0$, $ _{23} = /4$, $\tan^2 _{12} = 1/2$) to $\underline{\rm cobimaximal}$ mixing ($ _{13} \neq 0$, $ _{23} = /4$, $ _{CP} = \pm /2$

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

Search for the sterile neutrino mixing with the ICAL detector at INO
European Physical Journal C: Particles and Fields, 2017 The study has been carried out on the prospects of probing the sterile neutrino mixing with the magnetized iron calorimeter (ICAL) at the India-based Neutrino Observatory (INO), using atmospheric neutrinos as a source.

Non-zero $\theta_{13}$ and CP violation in a model with $A_4$ flavor symmetry
, 2012 Motivated by recent observations of non-zero $\theta_{13}$ from the Daya Bay and RENO experiments, we propose a renormalizable neutrino model with $A_4$ discrete symmetry accounting for deviations from the tri-bimaximal mixing pattern of neutrino mixing ...

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 ...

Nuclear Physics B, 2022 In this work, a flavour theory of a neutrino mass model based on A4 symmetry is considered to explain the phenomenology of neutrino mixing. The spontaneous symmetry breaking of A4 symmetry in this model leads to tribimaximal mixing in the neutrino sector

A Phenomenological Model of Effectively Oscillating Massless Neutrinos and Its Implications [PDF]
EPJ Web of Conferences, 2020 We discuss an alternative picture of neutrino oscillation. In this phenomenological model, the flavor-changing phenomena of massless neutrinos arise from scattering processes between neutrinos and four types of undetected spin-0 massive particles ...

Knitting neutrino mass textures with or without Tri-Bi maximal mixing
, 2011 The solar and baseline neutrino oscillation data suggest bimaximal neutrino mixing among the first two generations, and trimaximal mixing between all three neutrino flavors.

Seesaw mechanism and the neutrino mass matrix [PDF]
, 2000 The seesaw mechanism of neutrino mass generation is analysed under the following assumptions: (1) minimal seesaw with no Higgs triplets, (2) hierarchical Dirac masses of neutrinos, (3) large lepton mixing primarily or solely due to the mixing in the ...

Neutrino masses and neutrino mixing
Nuclear Physics B - Proceedings Supplements, 2006 We review the current (summer 2005) status of neutrino mass and mixing parameters, as emerging from a phenomenological analysis of world neutrino oscillation and non-oscillation data, performed within the standard three-neutrino mixing framework.
