强交互作用粒子

强交互作用粒子(Strongly interacting massive particles,缩写 SIMPs),是一种彼此间以强力作用的假设粒子。在碰撞星系阿贝尔 3827,它们似乎是被散射而看起来落后于普通物质的暗物质。尽管与普通物质有微弱的作用,它们还是被推断可能是暗物质[1]。然而,自那发现之后,根据对群集的进一步观测,就不在模型中给予考虑[2][3]

强相互作用例子被提出作为解决超高能宇宙射线的问题[4][5],以及没有冷却流的星系星团英语Cooling flow[6][7]

从1990年开始,各种实验和观测都对SIMP要成为暗物质产生了限制[8][9][10][11][12][13]

SIMP的湮灭会产生巨大的热量。DAMA实验受限于使用的Nal(TI)晶体[11][来源请求]

测量天王星的能量过剩排除SIMP在150MeV至104 GeV的可能[14]。地球的热流极大地限制了任何截面[15]
