| 内容記述 | We present the result of an indirect search for high energy neutrinos from WIMP annihilation in the Sun and in the Earth using upward-going muon events at Super-Kamiokande. Datasets from SKI-SKIII (3109.6 days) were used for the analysis. We looked for excesses of neutrino signal from the Sun and the Earth as compared with the expected atmospheric neutrino background in three types of upward-going muon categories: stopping, nonshowering, and showering. No significant excess was observed. The 90% C.L. upper limits of upward-going muon flux induced by WIMPs of 100 GeV/c2 which annihilate in the Sun were 2.1 ×10^3 km^−2 y^−1 and 1.3 ×10^3 km^−2 y^−1 for the soft and hard annihilation channels, respectively. Those of the Earth were 1.1 ×10^3 km^−2 y^−1 and 9.0 ×10^2 km^−2 y^−1 for the soft and hard annihilation channels, respectively. The flux limits from the Sun correspond to upper limits of 4.5 ×10^−3 pb and 2.7 ×10^−4 pb for spin-dependent WIMP-nucleon scattering cross sections in the soft and hard annihilation channels, respectively. Those from the Earth correspond to upper limits of 8.1×10^−6 pb and 7.0 ×10^−7 pb for spin-independent WIMP-nucleon scattering cross sections in the soft and hard annihilation channels, respectively. | |||||
