The Chinese Academy of Sciences announced that Chinese scientists have found strong evidence of the existence of the "Glueball," a hypothetical particle described as a "force particle."
A statement from the Academy indicated that scientists working on the Beijing Spectrometer III (BESIII) project provided data supporting the hypothesis that the X(2370) particle, discovered in 2011, may be a true "globula," that is, a rare particle made not of quarks, but of gluons, which are the particles that carry the strong nuclear force.
According to the statement, the study of this particle took about 15 years, during which the researchers concluded that its basic properties are consistent with the properties of the theoretically predicted globule, which is characterized by a spin and parity quantum number of 0⁻⁺.
Unlike conventional particles, such as protons and mesons, which are composed of quarks, globules are believed to be formed exclusively from gluons. Further evidence supporting this hypothesis, according to scientists, comes from the properties exhibited by the X(2370) particle.
The existence of globules was predicted by quantum chromodynamics (QCD), which describes the strong nuclear force. Experimental searches for these particles have continued for nearly half a century, and they remain one of the most significant open questions in modern physics. Confirmation of this discovery could lead to the discovery of a new type of matter composed of the same strong nuclear force carriers.
It is noted that the Beijing Spectrometer III (BESIII) project includes about 700 scientists from about 96 research institutions in 15 countries.
