Resolving Fermi, PAMELA and ATIC anomalies in split supersymmetry without R-parity
arXiv:0905.0652 · doi:10.1140/epjc/s10052-010-1317-3
Abstract
A long-lived decaying dark matter as a resolution to Fermi, PAMELA and ATIC anomalies is investigated in the framework of split supersymmetry (SUSY) without R-parity, where the neutralino is regarded as the dark matter and the extreme fine-tuned couplings for the long-lived neutralino are naturally evaded in the usual approach.
