Description
The conjectured bound state of uuddss in color-spin-flavor singlet can be a stable and compact particle, the sexaquark. Such a particle formed from QCD plasma in the early universe explains the observed dark matter abundance and can potentially resolve the 7Li puzzle. We will argue that a stable sexaquark may live in a rather wide mass window, either above two nucleon mass or below, because of three reasons: 1) the color-spin-flavor constraints, 2) the doubly-weak nature of the transition, and 3) the spatial suppression. Experimental limits on the spatial suppression from the SNO experiment will be discussed.
