These decay well afterthe electroweak phase transition, giving rise to B-ball baryogenesis. Being made of squarks, B-ball decays produce also LSPs and hence can be the source for all cold dark matter.5 pages, 1 postscript figure; talk given at the PASCOS-98 conferenceHigh Energy Physics - Phenomenologytext
