Sterile neutrino dark matter, CDMS-II and a light Higgs boson

, 2010
We add a singlet right handed neutrino plus a charged and a neutral singlet scalars to the standard model. This extension includes a discrete symmetry such that we obtain a heavy sterile neutrino which couples only to the electron and the new scalars. In

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 ...

Exploring a Non-Minimal Sterile Neutrino Model Involving Decay at IceCube and Beyond [PDF]

, 2017
We study the phenomenology of neutrino decay together with neutrino oscillations in the context of eV-scale sterile neutrinos. We review the formalism of visible neutrino decay in which one of the decay products is a neutrino that potentially can be ...

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.

Sterile neutrinos

Nature, 2011
In following we explain the necessity of existence of neutrinos and explain the theoretical basis of neutrino oscillations in vacuum and matter.

Sterile neutrinos and global symmetries [PDF]

Physical Review D, 2005
We use an effective-field-theory approach to construct models with naturally light sterile neutrinos, due to either exact or accidental global symmetries. The most attractive models we find are based on gauge symmetries, either discrete or continuous. We give examples of simple models based on Z_N, U(1)', and SU(2)'.

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,

Long-lived sterile neutrinos at Belle II in effective field theory

Journal of High Energy Physics, 2022
Large numbers of τ leptons are produced at Belle II. These could potentially decay into sterile neutrinos that, for the mass range under consideration, are typically long-lived, leading to displaced-vertex signatures.

Review of neutrino oscillations with sterile and active neutrinos [PDF]

International Journal of Modern Physics A, 2016
Recently neutrino oscillation experiments have shown that it is very likely that there are one or two sterile neutrinos. In this review neutrino oscillations with one, two, three sterile and three active neutrinos, and parameters that are consistent with experiments, are reviewed.
