“…The expected rates R ROI between 0.45 MeV < E vis < 1.6 MeV, which is the energy range of interest (ROI) chosen in this analysis, is also shown. The last row reports the current best experimental results for 7 Be and pep [12] and CNO [14] neutrinos obtained by the Borexino experiment (note that the pep results slightly depend on the HZ/LZ SSM predictions used for constraining CNO neutrino flux in the fit). All the rates are reported in cpd/kton units, which are counts per day per kton of scintillator.…”

“…As experienced by Borexino [13,14], the search for CNO neutrinos has two main obstacles: the low signal rate and the presence of several backgrounds existing on the same energy window, i.e. pep neutrinos, 11 C, and 210 Bi.…”

“…Borexino [11] has proven that the liquid scintillator technique is a suitable tool to study solar neutrinos with a low energy threshold, thanks to the good energy and position resolutions, and the pulse-shape discrimination capability. Borexino has performed a complete spectroscopy of solar neutrinos coming both from the "proton-proton" (pp) chain [12], which provides about 99% of the solar energy, and the CNO cycle [13,14]. Recently, Borexino also developed a Correlated Integrated Directionality (CID) method exploiting the sub-dominant Cherenkov light in order to disentangle a solar neutrino signal from an isotropic background [15,16].…”

Atmospheric neutrinos are one of the most relevant natural neutrino sources that can be exploited to infer properties about cosmic rays and neutrino oscillations. The Jiangmen Underground Neutrino Observatory (JUNO) experiment, a 20 kton liquid scintillator detector with excellent energy resolution is currently under construction in China. JUNO will be able to detect several atmospheric neutrinos per day given the large volume. A study on the JUNO detection and reconstruction capabilities of atmospheric $$\nu _e$$ ν e and $$\nu _\mu $$ ν μ fluxes is presented in this paper. In this study, a sample of atmospheric neutrino Monte Carlo events has been generated, starting from theoretical models, and then processed by the detector simulation. The excellent timing resolution of the 3” PMT light detection system of JUNO detector and the much higher light yield for scintillation over Cherenkov allow to measure the time structure of the scintillation light with very high precision. Since $$\nu _e$$ ν e and $$\nu _\mu $$ ν μ interactions produce a slightly different light pattern, the different time evolution of light allows to discriminate the flavor of primary neutrinos. A probabilistic unfolding method has been used, in order to infer the primary neutrino energy spectrum from the detector experimental observables. The simulated spectrum has been reconstructed between 100 MeV and 10 GeV, showing a great potential of the detector in the atmospheric low energy region.

“…Credit: APS/Alan Stonebraker information about the temperature and density of the solar interior, but uncertainties remain about the chemical ingredients. Now the Borexino Collaboration reports a new measurement of the neutrino flux produced by the so-called CNO hydrogen burning cycle in the Sun [1]. This cycle-which requires the presence of carbon (C), nitrogen (N), and oxygen (O)-produces neutrinos that carry enormous diagnostic power relating to the properties of the solar interior.…”

We determine the solar neutrino fluxes from the global analysis of the most up-to-date terrestrial and solar neutrino data including the final results of the three phases of Borexino. The analysis are performed in the framework of three-neutrino mixing with and without accounting for the solar luminosity constraint. We discuss the independence of the results on the input from the Gallium experiments. The determined fluxes are then compared with the predictions provided by the latest Standard Solar Models. We quantify the dependence of the model comparison with the assumptions about the normalization of the solar neutrino fluxes produced in the CNO-cycle as well as on the particular set of fluxes employed for the model testing.
