Improved Limits on Sterile Neutrino Dark Matter using Full-Sky Fermi Gamma-Ray Burst Monitor Data [PDF]

, 2015
A sterile neutrino of ~keV mass is a well motivated dark matter candidate. Its decay generates an X-ray line that offers a unique target for X-ray telescopes.

Probing active-sterile neutrino transition magnetic moment on coherent elastic solar neutrino-nucleus scattering

European Physical Journal C: Particles and Fields
In the presence of a transition magnetic moment between active and sterile neutrinos, sterile neutrinos could be produced by neutrino beams electromagnetically upscattering on nuclei.

Millimeter‐Wave WISP Search with Coherent Light‐Shining‐Through‐a‐Wall Toward the STAX Project

Annalen der Physik, Volume 536, Issue 1, January 2024.
This research article shows potential of millimeter waves for searching dark photons, one of the candidates of dark matter. By sharing a common reference signal, an excellent temporal coherency is achieved between production and detection of dark photons.

Chaotic Amplification of Neutrino Chemical Potentials by Neutrino Oscillations in Big Bang Nucleosynthesis [PDF]

, 1996
We investigate in detail the parameter space of active-sterile neutrino oscillations that amplifies neutrino chemical potentials at the epoch of Big Bang Nucleosynthesis.

A model for neutrino anomalies and IceCube data

Journal of High Energy Physics, 2019
We interpret the neutrino anomalies in neutrino oscillation experiments and the high energy neutrino events at IceCube in terms of neutrino oscillations in an extension of the standard model where three sterile neutrinos are introduced so as to make two ...

COSMOLOGY OF "VISIBLE" STERILE NEUTRINOS [PDF]

International Journal of Modern Physics A, 2005
We point out that in scenarios with a low reheating temperature TR << 100 MeV at the end of (the last episode of) inflation or entropy production, the abundance of sterile neutrinos becomes largely independent of their coupling to active neutrinos.

Statistical tests of sterile neutrinos using cosmology and short-baseline data [PDF]

, 2014
In this paper we revisit the question of the information which cosmology provides on the scenarios with sterile neutrinos invoked to describe the SBL anomalies using Bayesian statistical tests.

Exploring Light Sterile Neutrinos at Long Baseline Experiments: A Review

Universe, 2020
Several anomalies observed in short-baseline neutrino experiments suggest the existence of new light sterile neutrino species. In this review, we describe the potential role of long-baseline experiments in the searches of sterile neutrino properties and,

Apparent CPT Violation in Neutrino Oscillation Experiments

, 2010
We consider searching for light sterile fermions and new forces by using long baseline oscillations of neutrinos and antineutrinos. A new light sterile state and/or a new force can lead to apparent CPT violation in muon neutrino and antineutrino ...
