SIMP

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.

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.
