強交互作用粒子

強交互作用粒子(Strongly interacting massive particles,縮寫 SIMPs),是一種彼此間以強力作用的假設粒子。在碰撞星系阿貝爾 3827,它們似乎是被散射而看起來落後於普通物質的暗物質。儘管與普通物質有微弱的作用,它們還是被推斷可能是暗物質[1]。然而,自那發現之後,根據對群集的進一步觀測,就不在模型中給予考慮[2][3]

強相互作用例子被提出作為解決超高能宇宙射線的問題[4][5],以及沒有冷卻流的星系星團[6][7]

從1990年開始,各種實驗和觀測都對SIMP要成為暗物質產生了限制[8][9][10][11][12][13]

SIMP的湮滅會產生巨大的熱量。DAMA實驗受限於使用的Nal(TI)晶體[11]

測量天王星的能量過剩排除SIMP在150MeV至104 GeV的可能[14]。地球的熱流極大地限制了任何截面[15]
