RHIC

Kent State University researchers are part of a team of international scientists who have discovered antihelium-4, the most massive antinucleus known to date. This new discovery is the antimatter partner of the helium-4 nucleus, also called the alpha particle. Helium-4 is the normal form of helium, the second most abundant element in the universe after hydrogen.

Ten Kent State University researchers are part of a team of international scientists who have discovered the most massive antinucleus discovered to date. They are part of an international team of scientists studying high-energy collision of gold ions at the Relativistic Heavy Ion Collider (RHIC), a 2.4 mile-circumference particle accelerator at Brookhaven National Laboratory in Upton, N.Y., operated by the U.S. Department of Energy.
