Dark Matter Particle in QCD

Understand

We report on the possibility that the Dark Matter particle is a stable, neutral, as-yet-undiscovered hadron in the standard model.

• The existence of a compact color-flavor-spin singlet sexaquark (S, uuddss) with mass ~2m_p, is compatible with current knowledge.
• The S interacts with baryons primarily via a Yukawa interaction of coupling strength alpha_SN, mediated by omega and phi vector mesons having mass ~1 GeV.
• If it exists, the S is a very attractive DM candidate.
