Strongly interacting massive particle

Strongly interacting massive particles (SIMPs) are hypothetical particles that interact strongly with ordinary matter, but could form the inferred dark matter despite this.[1]

Strongly interacting massive particles have been proposed as a solution for the ultra-high-energy cosmic-ray problem[2][3] and the absence of cooling flows.[4][5] Various experiments and observations have set constraints on SIMP dark matter from 1990 onward.[6][7][8][9][10][11]

SIMPs annhilations would produce significant heat. DAMA set limits with NaITl crystals.[12]

Measurements of Uranus's heat excess exclude SIMPS from 150 MeV to 104 GeV. Earth's heat flow significantly constrains any cross section.[13]
