Scientists say they’ve found a particle made entirely of nuclear force Enter, glueball. After decades of searching, scientists say they’ve finally identified a glueball - a particle made purely of strong nuclear force. Hypothesised to exist as part of the standard model of particle physics, glueballs have eluded scientists since the 1970s because they can only be detected indirectly by measuring their process of decay. Now, a team of particle scientists in Austria say they've found evidence for the existence of glueballs by observing the decay of a particle known as f0(1710). Protons and neutrons - the particles that make up everyday matter - are made of minuscule elementary particles called quarks, and quarks are held together by even smaller particles called gluons. Also known as 'sticky particles', massless gluons are described as a complicated version of the photon, because just like how photons are responsible for exerting the force of electr...
