LHC breaks the document for heaviest antimatter nucleus ever observed

Another antimatter document has been damaged. In the smash-up of very lively lead ions, researchers have exposed proof of the heaviest antimatter model of an atomic nucleus ever observed.

In 2024, researchers from the STAR Collaboration at Brookhaven National Laboratory’s Relativistic Heavy Ion Collider (RHIC) in New York reported in brief making a then unprecedentedly heavy antimatter nucleus known as antihyperhydrogen-4.

Now, Benjamin Dönigus at Goethe University Frankfurt…
