Signal from sterile neutrino dark matter in extra U(1) model at direct detection experiment

Physics Letters B, 2020
We examine the possibility that direct dark matter detection experiments find decay products from sterile neutrino dark mater in U(1)B−L and U(1)R models.

Deviations in tribimaximal mixing from sterile neutrino sector

Nuclear Physics B, 2016
We explore the possibility of generating a non-zero Ue3 element of the neutrino mixing matrix from tribimaximal neutrino mixing by adding a light sterile neutrino to the active neutrinos.

Light Sterile Neutrinos

Journal of Physics: Conference Series, 2021
Abstract We review the status of light sterile neutrino searches, motivated by the original Short BaseLine (SBL) anomalies. Here, we discuss how sterile neutrino properties can be constrained by different types of neutrino oscillation experiments (considering appearance or disappearance probes in different oscillation channels) and non ...

Reionization in sterile neutrino cosmologies [PDF]

Monthly Notices of the Royal Astronomical Society, 2016
We investigate the process of reionisation in a model in which the dark matter is a warm elementary particle such as a sterile neutrino. We focus on models that are consistent with the dark matter decay interpretation of the recently detected line at 3.5 keV in the X-ray spectra of galaxies and clusters.

Hierarchically acting sterile neutrinos [PDF]

The European Physical Journal C, 2012
AbstractWe propose that a hierarchical spectrum of sterile neutrinos (eV, keV, 1013–15 GeV) is considered as the explanation for MiniBooNE and LSND oscillation anomalies, dark matter, and baryon asymmetry of the universe (BAU), respectively. The scenario can also realize the smallness of active neutrino masses by the seesaw mechanism.

θ23 Octant sensitivity in presence of light sterile and active ν and ν¯ oscillations using beamline experiments

Nuclear Physics B
We examine the octant sensitivity of the long-baseline neutrino oscillation experiments in view of light sterile neutrino flavors with masses in the 1 eV range. Considering the active-sterile mixing, we explore the possible preferred running modes either

Oscillations of Active Neutrinos at Short Baseline in the Model with Three Decaying Sterile Neutrinos

Universe, 2022
To study the oscillations of active neutrinos in the framework of the model with three active and three sterile neutrinos, the analytical expressions are obtained for the appearance and survival probabilities of different neutrino flavors taking into ...
