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 excludes significant regions of the parameter space relevant to hints from reactor and radioactive gallium source experiments. We then study the sensitivity of upcoming solar neutrino data, most notably elastic neutrino-electron scattering in… 

Statistical significance of the sterile-neutrino hypothesis in the context of reactor and gallium data

Abstract We evaluate the statistical significance of the 3+1 sterile-neutrino hypothesis using νe and $$ \overline{\nu} $$ ν ¯ e disappearance data from reactor, solar and gallium radioactive

Cosmology-friendly time-varying neutrino masses via the sterile neutrino portal

We investigate a consistent scenario of time-varying neutrino masses, and discuss its impact on cosmology, beta decay, and neutrino oscillation experiments. Such time-varying masses are assumed to be

Sterile Neutrino Search with MicroBooNE's Electron Neutrino Disappearance Data.

A sterile neutrino is a well motivated minimal new physics model that leaves an imprint in neutrino oscillations. Over the last two decades, a number of hints pointing to a sterile neutrino have

Quasi-sterile neutrinos from dark sectors. Part I. BSM matter effects in neutrino oscillations and the short-baseline anomalies.

Abstract Quasi-sterile neutrinos are a natural consequence of dark sectors interacting with the Standard Model (SM) sector via neutrino- and vector-portals. Essentially, quasi-sterile neutrinos are

We study the optimization of a green-field, two-baseline reactor experiment with respect to the sensitivity for electron antineutrino disappearance in search of a light sterile neutrino. We consider
