Examples from the web for gluon
  • Particle collisions hint at existence of undiscovered gluon.
  • Researchers have dubbed this state of matter the quark-gluon plasma.
  • The shattering can produce a quark-gluon plasma, a bulk form of quarks and gluons.
  • Hence two quarks in a meson are connected by this gluon-chromo-flux tube.
  • The second important reason to study photons at a hadron collider is to measure the gluon distribution inside the proton.
  • These results confirm the perfect liquid nature of quark-gluon plasma and tease out further details of its properties.
  • Scientists have always known that to calculate the position of every meson and gluon would be impossible, so they cheated.
  • At low transverse momentum, multiple soft gluon emission is expected to dominate the cross section.

gluon in Science
The subatomic particle that mediates the strong force. The exchange of gluons between two quarks changes the color of the quarks and results in the attractive force holding them together in hadrons. Gluons are bosons. See Table at subatomic particle.
