[1]sciencehabit shares a report from Science Magazine:
> For more than half a century, physicists have searched for one of the strangest particles predicted by modern theory. It would be made almost entirely of gluons, the elusive subatomic particles that carry the strong nuclear force. Now, using a particle collider in Beijing, researchers say they have effectively [2]proved the existence of such a "glueball ."
>
> In a preprint posted last month on arXiv and in [3]a presentation last week at the International Conference on High Energy Physics (ICHEP), the researchers argue that a particle called X(2370), which they produced by smashing electrons into positrons at high energies, has the properties expected of a glueball.
"It's an experimental triumph," says Colin Morningstar, a particle physicist at Carnegie Mellon University who was not involved in the finding. "It's the strongest evidence yet that particles dominated by a glueball component can exist in nature."
