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

eV-Scale Sterile Neutrinos [PDF]
Annual Review of Nuclear and Particle Science, 2019 We address the phenomenology of light sterile neutrinos, with an emphasis on short-baseline neutrino oscillations. After reviewing the observed short-baseline neutrino oscillation anomalies, we discuss the global fit of the data and the current appearance–disappearance tension.

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 ...

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.

Fixing the solar neutrino parameters with sterile neutrinos
Physical Review D, 2006 Neutrino mixing matrix appears to be close to bimaximal mixing, but for the solar mixing angle which is definitively smaller than forty five degrees. Whereas it seems quite easy to understand bimaximal mixing with the use of new global symmetries, as in models using $L_e - L_ - L_ $, understanding the about to eleven degrees of deviation in the ...

DARK MATTER AND STERILE NEUTRINOS [PDF]
The Eleventh Marcel Grossmann Meeting, 2008 Dark matter has been recognized as an essential part of matter for over 70 years now, and many suggestions have been made, what it could be. Most of these ideas have centered on Cold Dark Matter, particles that are predicted in extensions of standard particle physics, such as supersymmetry.

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 ...

Search for the sterile neutrino mixing with the ICAL detector at INO
European Physical Journal C: Particles and Fields, 2017 The study has been carried out on the prospects of probing the sterile neutrino mixing with the magnetized iron calorimeter (ICAL) at the India-based Neutrino Observatory (INO), using atmospheric neutrinos as a source.
