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.

Measuring the sterile neutrino CP phase at DUNE and T2HK
European Physical Journal C: Particles and Fields, 2018 The CP phases associated with the sterile neutrino cannot be measured in the dedicated short-baseline experiments being built to test the sterile neutrino hypothesis.

Detection of ultra high energy neutrinos by IceCube: Sterile neutrino scenario [PDF]
, 2013 The short-baseline neutrino oscillation experiments, the excess of radiation from the measurement of the cosmic microwave background radiation, the necessity of the nonbaryonic dark matter candidate and the depletion of the neutrino flux in IceCube all ...

Sensitivity to light sterile neutrino mixing parameters with KM3NeT/ORCA
Journal of High Energy Physics, 2021 KM3NeT/ORCA is a next-generation neutrino telescope optimised for atmospheric neutrino oscillations studies. In this paper, the sensitivity of ORCA to the presence of a light sterile neutrino in a 3+1 model is presented. After three years of data taking,

Numerical estimate of minimal active-sterile neutrino mixing
EPJ Web of Conferences, 2018 Seesaw mechanism constrains from below mixing between active and sterile neutrinos for fixed sterile neutrino masses. Signal events associated with sterile neutrino decays inside a detector at fixed target experiment are suppressed by the mixing angle to

Nuclear Physics B, 2022 We study the Peccei-Quinn (PQ) symmetry of the sterile right-handed neutrino sector and the gauge symmetries of the Standard Model. Due to four-fermion interactions, spontaneous breaking of these symmetries at the electroweak scale generates top-quark ...

New Journal of Physics, 2007 Neutrino masses are usually described by adding to the Standard Model some SU(2)-singlet fermions that have the Yukawa couplings, as well as some Majorana mass terms. The number of such fields and the scales of their Majorana masses are not known. Several independent observations point to the possibility that some of these singlets may have masses well
