摘要：
A search has been made for neutrinos from the diffuse supernova neutrino background (DSNB) using data collected during the first phase of the Sudbury Neutrino Observatory. No events are observed in the effective electron energy range of 21 MeV < T-eff < 35 MeV and, consequently, an upper limit on the v(e) component of the DSNB flux in the neutrino energy range of 22.9 MeV < E-v < 36.9 MeV of 70 cm(-2) s(-1) is inferred at the 90% confidence level. This is an improvement by two orders of magnitude on the previous upper limit on the v(e) component of the DSNB flux.
