Neutralino Clumps and Cosmic Rays | | Pierre Salati
; | | Date: |
18 Jan 2007 | | Abstract: | The halo of the Miky Way might contain numerous and dense substructures inside which the putative weakly interacting massive particles (suggested as the main constituent of the astronomical dark matter) would produce a stronger annihilation signal than in the smooth regions. The closer the nearest clump, the larger the positron and antiproton cosmic ray fluxes at the Earth. But the actual distribution of these substructures is not known. The predictions on the antimatter yields at the Earth are therefore affected by a kind of cosmic variance whose analysis is the subject of this contribution. The statistical tools to achieve that goal are presented and Monte Carlo simulations are compared to analytic results. | | Source: | arXiv, astro-ph/0701530 | | Services: | Forum | Review | PDF | Favorites | |
