Search for neutrinos from Gamma-Ray Bursts with the Baikal neutrino telescope NT200

Abstract

We present an analysis of neutrinos detected with the Baikal neutrino telescope NT200 for correlations with gamma-ray bursts (GRB). No neutrino events correlated with GRB were observed. Assuming a Waxman-Bahcall spectrum, a neutrino flux upper limit of {\bf $E^2 \Phi < 1.1 \times 10^{-6}cm^{-2}s^{-1}sr^{-1}GeV$} was obtained. We also present the Green's Function fluence limit for this search, which extends two orders of magnitude beyond the energy range of the Super-Kamiokande limit.
