A Stable H-Dibaryon: Dark Matter Candidate Within QCD?

Glennys R. Farrar

    Research output: Contribution to journalArticlepeer-review


    Particle physics arguments suggest that the H-dibaryon - a state consisting of two u, two d, and two s quarks-may have a mass ≈ 1.5 ± 0.2 MeV, and that rH ≲ 1/4 rN. Remarkably, the observed stability of nuclei and other experimental limits do not exclude this scenario at present, as discussed here. If they are present in sufficient abundance, relic H's would be the cold dark matter. Tests of this scenario are discussed.
