Axion-like particle assisted strongly interacting massive particle
arXiv:1704.04505 · doi:10.1103/PhysRevD.96.016007
Abstract
We propose a new realization of strongly interacting massive particles (SIMP) as self-interacting dark matter, where SIMPs couple to the Standard Model sector through an axion-like particle. Our model gets over 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 is within the reach of future beam dump experiments such as the Search for Hidden Particles (SHiP) experiment.
