Radiative emission of neutrino pairs in atoms and light sterile neutrinos

Physics Letters B, 2015
The process of Radiative Emission of Neutrino Pair (RENP) in atoms is sensitive to the absolute neutrino mass scale, the type of spectrum neutrino masses obey and the nature – Dirac or Majorana – of massive neutrinos.

Nuclear Effects and CP Sensitivity at DUNE

Advances in High Energy Physics, Volume 2020, Issue 1, 2020., 2020
The precise measurement of neutrino‐oscillation parameters is one of the highest priorities in neutrino‐oscillation physics. To achieve the desired precision, it is necessary to reduce the systematic uncertainties related to neutrino energy reconstruction.

Constraints on Neutrino Electric Millicharge from Experiments of Elastic Neutrino‐Electron Interaction and Future Experimental Proposals Involving Coherent Elastic Neutrino‐Nucleus Scattering

Advances in High Energy Physics, Volume 2020, Issue 1, 2020., 2020
In several extensions of the Standard Model of Particle Physics (SMPP), the neutrinos acquire electromagnetic properties such as the electric millicharge. Theoretical and experimental bounds have been reported in the literature for this parameter. In this work, we first carried out a statistical analysis by using data from reactor neutrino experiments,

Reconciling present neutrino puzzles: Sterile neutrinos as mirror neutrinos [PDF]

Physical Review D, 1995
We suggest that recent neutrino puzzles that are the solar and atmospheric neutrino deficits as well as the possible neutrino oscillations reported by the LSND experiment and the possibility of massive neutrinos providing the hot component of the cosmological dark matter, can all be naturally explained by assuming existence of a mirror world described ...

Dirac CP phases in a 3 + 1 neutrino scenario with $$\mu -\tau $$ μ - τ symmetry

European Physical Journal C: Particles and Fields, 2021
A sterile neutrino in the $$3+1$$ 3 + 1 scheme, where the sterile accounts for neutrino anomalies not explained solely by the weak active neutrinos, arises as a natural source for the breaking of the $$\mu -\tau $$ μ - τ symmetry suggested by oscillation

Probing heavy sterile neutrinos at neutrino telescopes via the dipole portal

Physics Letters B, 2023
The question of how heavy a sterile neutrino can be probed in experiments leads us to investigate the Primakoff production of heavy sterile neutrinos from ultrahigh-energy neutrinos via the magnetic dipole portal.

Sterile neutrinos with pseudoscalar self-interactions and cosmology [PDF]

, 2015
Sterile neutrinos in the electronvolt mass range are hinted at by a number of terrestrial neutrino experiments. However, such neutrinos are highly incompatible with data from the Cosmic Microwave Background and large scale structure. This paper discusses

DUNE Prospect for Leptophobic Dark Matter

Advances in High Energy Physics, Volume 2020, Issue 1, 2020., 2020
Highly energetic proton/electron beam fixed‐target experiments extend an opportunity to probe the sub‐GeV dark matter and associated interactions. In this work, we have explored the sensitivity of DUNE (Deep Underground Neutrino Experiment) for sub‐GeV leptophobic dark matter, i.e., this dark matter barely couples with the leptons.

An Algebraic Roadmap of Particle Theories

Annalen der Physik, Volume 537, Issue 4, April 2025.
The SO(10) grand unified theory, the Georgi–Glashow SU(5) grand unified theory, the Pati–Salam model, the Left–Right Symmetric model, and the Standard model have been studied extensively since the 1970s. Recasting these models in a division algebraic language elucidates how they are each in fact connected.

Update on neutrino mixing in the early Universe [PDF]

, 2001
From the current cosmological observations of CMB and nuclear abundances we show, with an analytic procedure, that the total effective number of extra neutrino species $\Delta N_{\nu}^{\rm tot}< 0.3$.
