In astrophysics SIMP is an abbreviation of Strongly Interacting Massive Particle. SIMPs could form the inferred dark matter despite their strong interactions with ordinary matter.B. D. Wandelt, R.

Steinhardt, "Self-Interacting Dark Matter", Marina del Rey 2000, Sources and detection of dark matter and dark energy in the universe, 263 (2000), [ preprint] .]

SIMPs have been proposed as a solution for the ultra high energy cosmic ray problemD. Chung, G. R. Farrar and E. W. Kolb, "Are ultrahigh energy cosmic rays signals of supersymmetry?", Phys. Rev.
