Meaning and Definition
An elementary particle that acts as the exchange particle for the strong force between quarks, binding them together to form protons, neutrons, and other hadrons.
The term is almost exclusively used in particle physics. It describes a massless, chargeless gauge boson that mediates the strong interaction, analogous to how the photon mediates the electromagnetic force. It carries the color charge, which is the source of the strong force.

Common Mistakes When Using “gluon”

FAQ
Frequently Asked Questions
Gluons are well-established in the Standard Model of particle physics. Their existence and properties are supported by extensive experimental evidence, such as from particle colliders like the LHC.
No, due to colour confinement, gluons (like individual quarks) are never found in isolation. They are always confined within composite particles like protons and neutrons.
There are eight independent types (or 'colour states') of gluons in quantum chromodynamics.
Both are gauge bosons (force carriers), but the photon mediates the electromagnetic force, is electrically neutral, and does not interact with itself. The gluon mediates the strong force, carries colour charge, and can interact with other gluons, making the strong force much more complex.
