強交互作用粒子

维基百科，自由的百科全书

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（英语：Cooling flow）[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][來源請求]。

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]。
