Accelerator search for cosmic SIMPs
Nuclear Physics B-Proceedings Supplements 124,(2003) 205-208;
We give limits on the contribution to the cosmic dark matter density of neutral, stable, strongly interacting massive particles (SIMPs). The limits axe inferred from an accelerator mass spectrometry (AMS) experiment at the Purdue Rare Isotope Measurement Laboratory (PRIME Lab). The experiment accelerated nuclei of both gold and iron. The "SIMP signal" would be discovery of nuclei of these elements with anomalous masses. Since no such signal was observed for SIMP masses up to over 1 TeV, cosmic SIMP density limits may be given. Determining the minimum time of exposure to SIMPs trapped in the galaxy is a crucial element in the analysis of each sample.
