Description
IceCube is the first neutrino telescope with TeV-PeV sensitivity sufficient
to constrain the prompt neutrino flux from Gamma Ray Bursts (GRBs). Limits based on data from the 40- and 59-string partially completed detector configurations have been published previously. Much of the parameter space for the previous generation of neutrino fluence models was excluded, which has encouraged continued theoretical work on more precise GRB fireball particle physics calculations. With data from the first year of the
completed 86-string detector, plus one year of the 79-string partial
detector, our analysis is now more sensitive to prompt neutrino emission
from GRBs by more than a factor of 2. We present results from analysis of
the latest data set as well as combined results including data from the 40-
and 59-string partial detector configurations.
