Physicists report new evidence that production of an exotic state of matter in collisions of gold nuclei at the Relativistic Heavy Ion Collider (RHIC)--an atom-smasher at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory--can be "turned off" by lowering the collision energy. The "off" signal shows up as a sign change--from negative to positive--in data that describe "higher order" characteristics of the distribution of protons produced in these collisions.
