Astronomy:Strongly interacting massive particle

From HandWiki
Short description: Hypothetical particle

Strongly interacting massive particles (SIMPs) are hypothetical particles that interact 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][citation needed]

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]
