A thermal calorimetric apparatus was designed, built and calibrated for measuring the activity of the artificial 144 Ce-144 Pr antineutrino source. This measurement will be performed at the Laboratori Nazionali del Gran Sasso in Italy, just before the source insertion in the tunnel under the Borexino detector and a precision better than 1% is...

The Borexino experiment is operational at Laboratori Nazionali del Gran Sasso since 2007. Its technical distinctive feature is the unprecedented ultralow background of the inner scintillating core, which is the basis of the outstanding achievements obtained by the experiment. After recalling the main features of the detector, we review the...

Neutrinos are impervious to the strong and electromagnetic forces and their minuscule weak interactions allow them to freely escape from the deep of the stars or of the Earth bringing precious information about regions otherwise inaccessible. Borexino is a large, unsegmented liquid-scintillator calorimeter in operation at the Laboratori...

Geo-neutrinos, electron anti-neutrinos produced in b-decays of naturally occurring radioactive isotopes in the Earth, are a unique direct probe of our planet's interior. After a brief introduction of the geo-neutrinos' properties and of the main aims of their study, we discuss the features of a detector which has recently provided breakthrough...

The Borexino experiment located in the Gran Sasso National Laboratory, is an organic liquid scintillator detector conceived for the real time spectroscopy of low energy solar neutrinos. The phase-I of the data taking campaign (2007 - 2010) has allowed the first independent measurements of 7 Be and pep solar neutrino fluxes as well as the first...

We review the solar neutrinos results of Borexino and the limit on the charge conservation obtained in the context of the analysis of the low energy region of the energy spectrum.

The Borexino detector has convincingly shown its outstanding performances in the low energy regime through its accomplishments in the observation and study of the solar and geo neutrinos. It is then an ideal tool to perform a state of the art source-based experiment for testing the longstanding hypothesis of a fourth sterile neutrino with ∼ eV...

The Borexino detector measures solar neutrino fluxes via neutrino-electron elastic scattering. Observed spectra are determined by the solar-νe survival probability Pee(E), and the chiral couplings of the neutrino and electron. Some theories of physics beyond the Standard Model postulate the existence of Non-Standard Interactions (NSI's) which...

In the recent years, the Borexino detector has proven its outstanding performances in detecting neutrinos and antineutrinos in the low energy regime. Consequently, it is an ideal tool to investigate the existence of sterile neutrinos, whose presence has been suggested by several anomalies over the past two decades. The SOX (Short distance...

We review the geoneutrino measurement with Borexino from 2056 days of data taking.
