Abstract We report on the search for anti-neutrinos of yet unknown origin with the Borexino detector at the Laboratori Nazionali del Gran Sasso. In particular, a hypothetical anti-neutrino flux from the Sun is investigated. Anti-neutrinos are detected through the neutron inverse β decay reaction in a large liquid organic scintillator target. We set a new upper limit for a hypothetical solar ν ¯ e flux of 760 cm − 2 s − 1 , obtained assuming an undistorted solar 8 B energy spectrum. This… CONTINUE READING
