Researchers at Berkeley Lab and their collaborators have
honed a way to probe the quark-gluon plasma, the kind of matter that dominated
the universe immediately after the big bang.
By combining data from two high-energy accelerators, nuclear
scientists have refined the measurement of a remarkable property of exotic
matter known as quark-gluon plasma. The findings reveal new aspects of the
ultra-hot, “perfect fluid” that give clues to the state of the young universe
just microseconds after the big bang.
