Atmospheric and solar neutrino oscillations in νMSSM and beyond [PDF]

Physics Letters B, 1999
We show how a unified description of the various two-flavor neutrino oscillation solutions, allowed by the atmospheric and solar neutrino experiments, are naturally realized within the framework of $ $MSSM (MSSM augmented with the seesaw mechanism) and beyond, especially grand unified theories.

Neutrino non-standard interactions and dark matter searches with multi-ton scale detectors

Journal of High Energy Physics, 2018
Future dark matter (DM) direct detection searches will be subject to irreducible neutrino backgrounds that will challenge the identification of an actual WIMP signal in experiments without directionality sensitivity. We study the impact of neutrino-quark

Solar active-sterile neutrino conversion with atomic effects at dark matter direct detection experiments

Journal of High Energy Physics, 2022
The recent XENON1T excess can be explained by the solar active-sterile neutrino conversion with bound electrons via light mediator. Nevertheless, the atomic effects are usually omitted in the solar neutrino explanations.

Vacuum and MSW interpretations of solar neutrino data with the LNW mass matrix [PDF]

, 2000
The Lehmann-Newton-Wu mass matrix, which was recently applied to neutrinos, is further investigated. The analytic results presented earlier are confirmed numerically for the solar density profile of the Standard Solar Model.

Neutrino Oscillations in Brans-Dicke Theory of Gravity [PDF]

, 1999
Flavor oscillations of neutrinos are analyzed in the framework of Brans-Dicke theory of gravity. We find a shift of quantum mechanical phase of neutrino proportional to $G_N\Delta m^2$ and depending on the parameter $\omega$. Consequences on atmospheric,

On the determination of leptonic CP violation and neutrino mass ordering in presence of non-standard interactions: present status

Journal of High Energy Physics, 2019
We perform a global analysis of neutrino data in the framework of three massive neutrinos with non-standard neutrino interactions which affect their evolution in the matter background. We focus on the effect of NSI in the present observables sensitive to

The ν R -philic scalar: its loop-induced interactions and Yukawa forces in LIGO observations

Journal of High Energy Physics, 2020
Right-handed neutrinos (ν R ) are often considered as a portal to new hidden physics. It is tempting to consider a gauge singlet scalar (ϕ) that exclusively couples to ν R via a ν R ν Rϕ term.

Global analysis of three-flavour neutrino oscillations: synergies and tensions in the determination of θ 23, δ CP, and the mass ordering

Journal of High Energy Physics, 2019
We present the results of a global analysis of the neutrino oscillation data available as of fall 2018 in the framework of three massive mixed neutrinos with the goal at determining the ranges of allowed values for the six relevant parameters.

Testing maximal electron and muon neutrino oscillations with sub-GeV SuperKamiokande atmospheric neutrino data [PDF]

, 1997
Motivated by the Exact Parity Model and other theories, the hypothesis that each of the known neutrinos oscillates maximally with a sterile partner has been put forward as an explanation of the atmospheric and solar neutrino anomalies.

Wolfenstein potentials for neutrinos induced by ultra-light mediators

Journal of High Energy Physics, 2019
New physics can emerge at low energy scales, involving very light and very weakly interacting new particles. These particles can mediate interactions between neutrinos and usual matter and contribute to the Wolfenstein potential relevant for neutrino ...
