Abstract
We propose a new realization of strongly interacting massive particles (SIMPs) as self-interacting dark matter, where SIMPs couple to the standard model (SM) sector through an axionlike particle. Our model overcomes major obstacles accompanying the original SIMP model, such as a missing mechanism of kinetically equilibrating SIMPs with the SM plasma as well as marginal perturbativity of the chiral Lagrangian density. Remarkably, the parameter region realizing σself/mDM≃0.1-1 cm2/g is within the reach of future beam dump experiments such as the Search for Hidden Particles experiment. © 2017 American Physical Society
