In particle physics, a glueball (also gluonium, gluon-ball) is a hypothetical composite particle. [1] It consists solely of gluon particles, without valence quarks . Such a state is possible because gluons carry color charge and experience the strong interaction between themselves.

2024年5月7日 · It is now the most compelling, interesting candidate for a glueball: a species of composite particle that should exist, but that has never been seen before.

2024年5月12日 · Plus of course, we now have the equipment and instruments necessary to peer into the most fundamental workings of the natural world, and to produce the billions of particle states required to spot something as rare and exotic as a glueball. The research has been published in Physical Review Letters.

2015年10月20日 · A glueball is an exotic particle, made up entirely of gluons – the “sticky” particles that keep nuclear particles together. Glueballs are unstable and can only be detected indirectly, by analyzing their decay.

2024年5月16日 · Scientists potentially uncovered a glueball particle, an enigmatic entity believed to be made entirely of the strong nuclear force's gluons.

2024年5月8日 · The result would be a glueball. For this new study, the research team was looking for evidence of glueballs.
