Abstract
We calculate, for a number of cases, the cosmic temperature at which primordial quarks condense into baryons, within a field theory of partially confined quarks that enjoys temporary asymptotic freedom. We assume that the mass of a quark in a dense quark-antiquark medium is a monotonic function of the medium—that is, we assume the validity of the so-called "Archimedes effect." We show that, within such models, unbound-quark lifetimes are larger than the age of the universe at the time of the transition and that
