X(2370) particle provides strongest evidence yet for glueball existence
↗
Researchers report that a particle called X(2370), produced by smashing electrons into positrons at a Beijing collider, has properties expected of a glueball, offering the strongest evidence yet for such particles.
This finding would confirm a half-century-old prediction about particles made almost entirely of gluons, the carriers of the strong nuclear force. It validates the theoretical framework that describes nuclear interactions, though its immediate practical impact on engineering is limited. The result also demonstrates the value of large-scale experimental facilities in testing fundamental physics.

The particle X(2370) was produced by smashing electrons into positrons at a particle collider in Beijing.
Researchers argue that X(2370) has the properties expected of a glueball, a particle made almost entirely of gluons.
An outside physicist calls the finding the strongest evidence yet that glueball-dominated particles can exist in nature.
