摘要：

The minimal supersymmetric standard model has a truly supersymmetric way of explaining both the baryon asymmetry and cold dark matter in the present Universe: that is, "Affleck-Dine baryo/DM genesis." The associated late-time decay of Q balls directly connects the origins of the baryon asymmetry and dark matter, and also predicts a specific nature of the LSP. In this paper, we investigate the prospects for indirect detection of these dark matter candidates observing the high-energy neutrino flux from the Sun and hard positron flux from the halo. We also update the previous analysis of the direct detection of Fujii and Hamaguchi [Phys. Rev. D 66, 083501 (2002)] by implementing the recent results from the WMAP satellite.
