Scientists in the STAR collaboration at the Relativistic Heavy Ion Collider (RHIC, http://www.bnl.gov/rhic/), a particle accelerator exploring nuclear physics and the building blocks of matter at the U.S. Department of Energy's Brookhaven National Laboratory, have new evidence for what's called a "chiral magnetic wave" rippling through the soup of quark-gluon plasma created in RHIC's energetic particle smashups.
The presence of this wave is one of the consequences scientists were expecting to observe in the quark-gluon plasma--a state of matter that existed in the early universe when quarks and gluons, the building blocks of protons and neutrons, were free before becoming inextricably bound within those larger particles. The tentative discovery, if confirmed, would provide additional evidence that RHIC's collisions of energetic gold ions recreate nucleus-size blobs of the fiery plasma thousands of times each second. It would also provide circumstantial evidence in support of a separate, long-debated quantum phenomenon required for the wave's existence. The findings are described in a paper that will be highlighted as an Editors' Suggestion in Physical Review Letters.
