Researchers have found evidence of an exotic form of antimatter in the aftermath of colliding extremely fast lead ions.
Benjamin Dönigus at Goethe University Frankfurt and colleagues from the Large Hadron Collider at the Geneva CERN particle physics laboratory have created an unprecedentedly heavy antimatter nucleus: antihyperhelium-4.
