Abstract content

This work presents a search for low-energy neutrino signal in Borexino detector in coincidence with the gravitational wave (GW) events GW150914, GW151226 and GW170104. Correlated neutrino events were searched with visible energies greater than 250~keV within a time window of $\pm$500~s centered around the GW detection time. A total of five candidates were found for all three GW events combined. The number of events found is consistent with the expected number of solar neutrino and background events. As a result, we have obtained the best current upper limits on the GW event neutrino fluence of all flavors $(\nu_e, \nu_{\mu}, \nu_{\tau})$ in the neutrino energy range (0.5 -- 5.0) MeV.
