The Borexino experiment is taking data since 2007 at the „Laboratori Nazionali del Gran Sasso“ in Italy accomplishing outstanding achievements in the field of neutrino physics. Its success is strongly based on the unprecedented ultra-high radio-purity of the inner scintillator core.
In this talk, after introducing the main features of the detector, the impressive results for solar and...

Solar flares are sudden variations in brightness observed near the Sun's surface. Some theorethical models predict production of electron and muon neutrinos with energies up to few tens of MeV during solar flares. In 1980th the Homestake experiment reported excess of detected neutrino events possibly correlated with large solar flares. Since then the interest to similar studies by other...

Atmospheric neutrinos are produced in interactions of cosmic rays with atomic nuclei in the Earth’s atmosphere. In low energy neutrino experiments they mainly considered as a background for studied processes. For atmospheric neutrinos in energy range below 1 GeV we present semi-analytical expected yield for four neutrino detection reactions: νp-ES, νe-ES, inverse β-decay and 12C(ν,...

The Troitsk $\nu$-mass experiment was starter in the 1985 and was initially intended to search for the mass of electron neutrino. Currently it give the best direct upper limit on that mass. In 2012, after reanalyzing old data for traces of relatively light sterile neutrinos (with masses up to 200 eV), the setup was modified to search for sterile neutrinos in a wider range (up to 3 keV and in...

High-intensity artificial Cr-51 sources are used to calibrate solar neutrino detectors. The necessary amount of Cr-51 can be obtained by irradiating chromium enriched in Cr-50 in a thermal neutron trap of the SM-3 high-flux reactor in JSC “SSC RIAR”. The paper presents the analysis of irradiation options both using the existing trap and advanced trap designs to be used during the reactor...

The current status of the short baseline experiment BEST with a 3MCi 51Cr artificial neutrino source to search for transitions of electron neutrinos to sterile states on the Gallium Germanium Neutrino Telescope at the Baksan Neutrino Observatory INR RAS is presented. The experiment has the great potential to search for transitions of active neutrinos to sterile states with Δm2~ 1 eV2 and to...

The report presents the results of measurements of the spectrum of internal bremsstrahlung (IB) Cr51. The isotope Cr51 was used for production of intense neutrino sources for calibrations of gallium solar neutrino detectors. By measuring the IB spectrum Cr51 it is planned to determine the source activity in the experiment BEST to search for sterile neutrino in gallium target.

Recent data of reactor neutrino experiments give a hint for anomalously low antineutrino flux at short distances.
A possible explanation of this anomaly is the presence of sterile neutrinos.
SOX project is based on the idea of placing a neutrino source close to a large volume detector in order to look for the flux suppression and the oscillation pattern inside the detector volume. In this...
