Strongly interacting massive particle explained

A strongly interacting massive particle (SIMP) is a hypothetical particle that interacts strongly between themselves and weakly with ordinary matter, but could form the inferred dark matter despite this.[1] [2] [3]

Strongly interacting massive particles have been proposed as a solution for the ultra-high-energy cosmic-ray problem[4] [5] and the absence of cooling flows in galactic clusters.[6] [7]

Various experiments and observations have set constraints on SIMP dark matter from 1990 onward.[8] [9] [10] [11] [12] [13]

SIMP annihilations would produce significant heat. DAMA set limits with NaI(Tl) crystals.[11]

Measurements of Uranus's heat excess exclude SIMPs from 150 MeV to 104 GeV.[14] Earth's heat flow significantly constrains any cross section.[15]
