Details of the recent measurement of the Solar pp-neutrino flux will be reported. This measurement completes the measurement of Solar neutrino fluxes from the pp-chain of reactions in Borexino experiment. The result is in agreement with the prediction of the Standard Solar Model and the MSW/LMA oscillation scenario.

Borexino is a liquid scintillator detector primary designed to observe solar neutrinos. Due to its low background level as well as its position in a nuclear free country, Italy, Borexino is also sensitive to geo-neutrinos. Borexino is leading this interdisciplinary field of neutrino geoscience by studying electron antineutrinos which are emitted from the decay of radioactive isotopes present...

The detection of neutrinos emitted in the CNO reactions in the Sun is one of the
ambitious goals of Borexino Phase-II.
A measurement of CNO neutrinos would be a milestone in astrophysics, and would allow to solve serious issues in current solar models.
A precise measurement of the rate of neutrinos from the pep reaction would allow to
investigate neutrino oscillations in the MSW...

The new limit on the electron lifetime is obtained from data of Borexino experiment.
The expected signal from the $e\rightarrow\gamma\nu$ decay mode is 256 keV photon detected in liquid scintillator.
Because of extremely low radioactive background level in Borexino detector it was possible to improve the previous measurement by two orders of magnitude.

Atmospheric neutrinos are produced in interactions of cosmic rays with atomic nuclei in the Earth’s atmosphere. Although their flux is too low for studying in Borexino, atmospheric neutrinos act as a background for other processes.
This talk presents the theoretical expected yield of atmospheric neutrinos in Borexino for three neutrino detection reactions: νp-ES, νe-ES and inverse β-decay, as...

Gamma-ray bursts (GRBs) are the most energetic known events in the Universe. Though gamma-ray telescopes observe about one GRB event per day, the nature of this phenomenon is not yet tottaly understood. Many theoterical models predict emission of neutrinos of all types in a wide energy range. In this talk we review experimental searches of GRB neutrinos in MeV energy range. The searches of...
