Dynamical evolution of the Universe in the quark-hadron phase transition and nugget formation - art. no. 063505

We study the dynamics of a first-order phase transition in the early Univer se when it was 10-50 mu s old with quarks and gluons condensing into hadron s. We look at the evolution of the Universe in small as well as large super cooling scenarios, specifically exploring the formation of quark nuggets, t heir possible survival and identification with the recently observed dark o bjects in our galactic halo which may account for the dark matter component in the Universe.
