Beijing collider team reports clearest evidence yet that X(2370) is a glueball particle
↗
Researchers at the Beijing Electron Positron Collider II have identified the clearest evidence yet that the known particle X(2370) is dominated by a glueball state, a particle composed entirely of gluons, the force carriers of the strong interaction.
If confirmed, this validates a nearly 50-year-old theoretical prediction that gluons can bind together into a new form of matter, the only particle type composed purely of force mediators. However, the researchers note more experiments are needed to further confirm the result.
Written by elseif from the cluster below · every claim links back to a sourceThe three things worth knowing
The collaboration determined X(2370) has flavor-singlet nature, described as the most important characteristic of a glueball
Prior work published in Physical Review Letters in 2024 analyzed 10 billion meson decay events and measured X(2370)'s mass and spin parity, finding agreement with predictions
The researchers describe this as the clearest experimental result from nearly 50 years of glueball searches
