Summary
These particles are called gluons, and when they stick together they form a glueball.
It would be the first example of matter made just from force carriers.
Researchers are excited but need more proof.
Key Points
4 points1
A glueball is a particle made only of gluons.
2
Gluons are the carriers of the strong nuclear force.
3
The discovery would show a new form of matter.
4
Further experiments are required to be sure.
