Search for Dark Matter WIMPs Using Upward-Going Muons in Super-Kamiokande

摘要

We present the results of indirect searches or Weakly Interacting Massive Particles (WIMPs) with the Super-Kamiokande detector using neutrino-induced upward through-going muons. The search is done by looking for a statistically significant excess of upward muons from the Sun, the core of the Earth, and the Galactic Center as compared to the number expected from the atmospheric neutrino background. No such excess was seen; therefore we calculate flux limits in various angular cones around each of the above celestial objects. These flux limits are then compared with previous estimates by other detectors. For the Sun and the Earth these flux limits are calculated as a function of WIMP masses.
