SIMP (Strongly Interacting Massive Particle) Search
  We consider laboratory experiments that can detect stable, neutral strongly interacting massive particles (SIMPs). We explore the SIMP annihilation cross section from its minimum value (restricted by cosmological bounds) to the barn range, and vary the mass values from a GeV to a TeV.   We also consider the prospects and problems of detecting such particles at the Tevatron.
