In this paper, we report the first measurement of CNO solar neutrinos by Borexino that uses the correlated integrated directionality (CID) method, exploiting the subdominant Cherenkov light in the liquid scintillator detector. The directional information of the solar origin of the neutrinos is preserved by the early Cherenkov photons from the...

Cosmogenic C-11 is produced in-situ by atmospheric mons and forms the main background for the measurement of solar pep- and CNO-neutrinos. However, FLUKA simulations show that the majority of C-11 is accompanied by a free neutron in the final state, thus allowing for an efficient tagging method, the so-called Three-Fold Coincidence technique....
