Discovery STAR

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.
