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 [1].
SIMPs have been proposed as a solution for the ultra high energy cosmic ray problem [2,3] and for the absence of cooling flows [4,5]. Constraints from various experiments and observations on SIMP dark matter are given in [1,6,7,8,9,10].
