Abstract

A search was conducted to detect the diffuse signal of ν̄e from all previous core-collapse supernovae. No appreciable signal was detected in 1496 days of SK data. Using various models, 90% C.L. limits were set on the total SRN flux. A limit of 1.2 ν̄e cm-2s-1 was set for the SRN flux above a threshold of Ev > 19.3 MeV.
