Proton-nuclei smashups yield clues about 'quark gluon plasma'
Houston TX (SPX) Apr 12, 2017
Findings from Rice University physicists working at Europe's Large Hadron Collider (LHC) are providing new insight about an exotic state of matter called the "quark-gluon plasma" that occurs when protons and neutrons melt. As the most powerful particle accelerator on Earth, the LHC is able to smash together the nuclei of atoms at nearly the speed of the light. The energy released in these collisions is vast and allows physicists to recreate the hot, dense conditions that existed in the early unive ... read more
