Journal Article

We present the result of an indirect search for high energy neutrinos from Weakly Interacting Massive Particle (WIMP) annihilation in the Sun using upward-going muon (upmu) events at Super-Kamiokande. Data sets from SKI-SKIII (3109.6days) were used for the analysis. We looked for an excess of neutrino signal from the Sun as compared with the expected atmospheric neutrino background in three upmu categories: stopping, non-showering, and showering. No significant excess was observed. The 90% C.L. upper limits of upmu flux induced by WIMPs of 100GeV c-2 were 6.4 × 10-15cm -2s-1 and 4.0 × 10-15cm -2s-1 for the soft and hard annihilation channels, respectively. These limits correspond to upper limits of 4.5 × 10 -39cm-2 and 2.7 × 10-40cm-2 for spin-dependent WIMP-nucleon scattering cross sections in the soft and hard annihilation channels, respectively. © 2011.
