CU Physics Professor Jamie Nagle is a group leader in a new discovery about the quark-gluon plasma. Researchers at the PHENIX detecter at Brookhaven's Relativistic Heavy Ion Collider made an unexpected discovery during an experiment that creates a quark-gluon plasma, the type of matter that existed in the first few millionths of a second after the Big Bang! They found that the quark-gluon plasma can exist in droplets far smaller than previously thought. Professor Nagle is the co-spokesperson for the experiment. Assistant Professor Romatschke's theoretical modeling of the relativistic hydrodynamics of the quark-gluon plasma in highlighted in the press release.
