glueballleaning
Glueballleaning is a term that describes a theoretical concept within quantum chromodynamics (QCD), the theory of the strong nuclear force. It refers to a hypothetical state of matter composed entirely of gluons, the force-carrying particles of the strong force, without any valence quarks. In standard hadrons, like protons and neutrons, quarks are the fundamental building blocks, and gluons mediate the interactions between them. Glueballs, by contrast, are "pure gluon" states.
The existence of glueballs is predicted by QCD, but they have not yet been definitively observed experimentally.
Experimental searches for glueballs have been ongoing for decades, primarily in high-energy particle physics experiments. Various
