Query: Search for Tens of MeV Neutrinos associated with Gamma-Ray Bursts in
  Super-Kamiokande   A search for neutrinos produced in coincidence with Gamma-Ray Bursts(GRB) was
conducted with the Super-Kamiokande (SK) detector. Between December 2008 and
March 2017, the Gamma-ray Coordinates Network recorded 2208 GRBs that occurred
during normal SK operation. Several time windows around each GRB were used to
search for coincident neutrino events. No statistically significant signal in
excess of the estimated backgrounds was detected. The $\bar\nu_e$ fluence in
the range from 8 MeV to 100 MeV in positron total energy for
$\bar\nu_e+p\rightarrow e^{+}+n$ was found to be less than $\rm 5.07\times10^5$
cm$^{-2}$ per GRB in 90\% C.L. Upper bounds on the fluence as a function of
neutrino energy were also obtained.
