Relics of Cosmic Quark- Hadron Phase Transition and Massive Compact Halo Objects

Abstract

We propose that the cold dark matter (CDM) is composed entirely of quark matter, arising from a cosmic quark-hadron transition. We show that compact gravitational objects, with masses around 0.5 (M_{\odot}), could have evolved out of the such CDM.
