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.

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

Checking T and CPT violation with sterile neutrino

Nuclear Physics B, 2016
Post LSND results, sterile neutrinos have drawn attention and motivated the high energy physics, astronomy and cosmology to probe physics beyond the standard model considering minimal 3+1 (3 active and 1 sterile) to 3+N neutrino schemes.

Testing sterile neutrino mixing with present and future solar neutrino data

European Physical Journal C: Particles and Fields, 2022
We investigate the sensitivity of solar neutrino data to mixing of sterile neutrinos with masses $$\gtrsim $$ ≳  eV. For current data, we perform a Feldman–Cousins analysis to derive a robust limit on the sterile neutrino mixing. The solar neutrino limit

Berry Phase in Neutrino Oscillations

, 2004
We study the Berry phase in neutrino oscillations for both Dirac and Majorana neutrinos. In order to have a Berry phase, the neutrino oscillations must occur in a varying medium, the neutrino-background interactions must depend on at least two ...

Are there sterile neutrinos at the eV scale?

, 2011
New predictions for the anti-neutrino flux emitted by nuclear reactors suggest that reactor experiments may have measured a deficit in the anti-neutrino flux, which can be interpreted in terms of oscillations between the known active neutrinos and new ...

Sterile neutrino-enhanced supernova explosions [PDF]

Physical Review D, 2007
We investigate the enhancement of lepton number, energy, and entropy transport resulting from active-sterile neutrino conversion $ _e\to _s$ deep in the post-bounce supernova core followed by re-conversion $ _s\to _e$ further out, near the neutrino sphere.

A search for sterile neutrinos with the latest cosmological observations

European Physical Journal C: Particles and Fields, 2017
We report the result of a search for sterile neutrinos with the latest cosmological observations. Both cases of massless and massive sterile neutrinos are considered in the $$\Lambda $$ Λ CDM cosmology.
