Self-heating of strongly interacting massive particles

Primordial nucleosynthesis constraint on massive, stable, strongly interacting particles

Heavy, stable, strongly interacting massive particles (X), have recently been discussed by many authors in theoretical and phenomenological contexts. We address the question of constraints on these particles from searches for anomalous nuclei containing them that would be formed during primordial nucleosynthesis. Based on existing data and previous investigations of primordial nucleosynthesis o...

Nucleosynthesis constraints on massive, stable, strongly interacting particles

We find constraints on heavy, stable, strongly interacting massive particles (X) from searches for anomalous nuclei containing them, formed during primordial nucleosynthesis. Using existing data, we obtain a limit on the abundance ratio CX ≡ nX/nB in the range of 3×10 −8 to 3×10−13 for masses up to 10 TeV if the X − N interaction is sufficiently strong to bind in low Z nuclei. We also find a ro...

Superweakly interacting massive particles.

We investigate a new class of dark matter: superweakly interacting massive particles (super-WIMPs). As with conventional WIMPs, super-WIMPs appear in well motivated particle theories with naturally the correct relic density. In contrast to WIMPs, however, super-WIMPs are impossible to detect in all conventional dark matter searches. We consider the concrete examples of gravitino and graviton co...

Cracking Open the Window for Strongly Interacting Massive Particles as the Halo Dark Matter

In the early 1990's, an analysis was completed by several theorists of the available mass/cross-section parameter space for unusual particle candidates to solve the dark matter problem, e.g. strongly interacting massive particles (SIMPs). This analysis found several unconstrained windows , such that for SIMP masses and cross-sections within these windows, SIMPs could still be the dominant dark ...
