Supernova relic neutrino search at super-Kamiokande

Published

Journal Article

A new Super-Kamiokande search for supernova relic neutrinos was conducted using 2853 live days of data. Sensitivity is now greatly improved compared to the 2003 Super-Kamiokande result, which placed a flux limit near many theoretical predictions. This more detailed analysis includes a variety of improvements such as increased efficiency, a lower energy threshold, and an expanded data set. New combined upper limits on supernova relic neutrino flux are between 2.8 and 3.1ν ̄ecm -2s -1>16MeV total positron energy (17.3MeV E ν). © 2012 American Physical Society.
