TL;DR
This paper describes a search for astrophysical neutrino signals from sources like gamma-ray bursts and solar flares using SNO, employing a new coincidence detection method, but finds no such correlations.
Contribution
Introduces a novel method for detecting temporal coincidences between neutrino events and astrophysical bursts in SNO data.
Findings
No correlations found between neutrinos and astrophysical sources
New coincidence detection method developed
Supports the absence of detectable neutrino signals from these sources
Abstract
The Sudbury Neutrino Observatory (SNO) has confirmed the standard solar model and neutrino oscillations through the observation of neutrinos from the solar core. In this paper we present a search for neutrinos associated with sources other than the solar core, such as gamma-ray bursters and solar flares. We present a new method for looking for temporal coincidences between neutrino events and astrophysical bursts of widely varying intensity. No correlations were found between neutrinos detected in SNO and such astrophysical sources.
