Description

A search for Supernova Relic neutrinos in the energy range 13.3 MeV $< E_{\bar{\nu}_e} <$ 31.3 MeV with neutron tagging at Super-Kamiokande-IV is conducted. We identify 13 inverse-beta-decay candidates, all of which can be attributed to background. In the absence of signal, 90\% C.L. upper limits are calculated with respect to different models. A differential flux upper limit is also given with no model dependence.
