Researchers at the Beijing Electron Positron Collider have presented the strongest evidence yet for the existence of the 'glueball,' a particle made entirely of gluons, after 15 years of study.
The particle, designated X(2370) with a mass of 2,370 million electron volts, was identified through a rigorous checklist of tests confirming its properties as a 'flavour singlet'.
Physicists conclude that X(2370) is dominated by a glueball structure, marking a significant breakthrough in quantum theory that could potentially lead to future technological applications.
