Latest Gluon Stories

Using high-speed collisions between gold atoms, scientists think they have re-created one of the most mysterious forms of matter in the universe -- quark-gluon plasma. This form of matter was present during the first microsecond of the Big Bang and may still exist at the cores of dense, distant stars.UC Davis physics professor Daniel Cebra is one of 543 collaborators on the research. His main role was building the electronic listening devices that collect information about the collisions, a...

New results from a particle collider suggest that the universe behaved like a liquid in its earliest moments, not the fiery gas that was thought to have pervaded the first microseconds of existence. By revising physicists' concept of the early universe, the new discovery offers opportunities to better learn how subatomic particles interact at the most fundamental level. It may also reveal intriguing parallels between gravity and the force that holds atomic nuclei together, physicists said...

Washington -- Scientists trying to recreate conditions that existed just a few millionths of a second after the big bang that started the universe have run into a mysterious problem "“ some of the reactions they are getting don't mesh with what they thought they were supposed to see. Now, two University of Washington physicists have dusted off a quantum mechanics technique usually associated with low-energy physics and applied it to results from experiments at Brookhaven National Laboratory...
