Gluons are the force-carrying particles that bind quarks together to form protons and neutrons, the building blocks of atomic nuclei. They are the carriers of the strong force, one of the four fundamental forces of nature. Gluons are massless elementary particles that mediate the strong interaction between quarks, acting as the exchange particle for the interaction. They are vector bosons with a spin of 1 and carry a type of charge called color charge, which comes in three types: red, green, and blue. The theory that describes the strong nuclear force involving gluons is called Quantum Chromodynamics (QCD), which is a notoriously difficult theory to solve. In particle physics, the electroweak interaction or force is the unified description of two of the fundamental interactions of nature: electromagnetism and the weak interaction. The electroweak force is thought to have split into the electromagnetic and weak force during the quark epoch shortly after the Big Bang. Thus, the electroweak force is not one of the four fundamental forces of nature, unlike the strong force carried by gluons.

What You'll Learn
Gluons are the carriers of the strong force
The strong force is the expression of the gluon interaction with other quark and gluon particles. Gluons play an important role in the elementary strong interactions between quarks and gluons, described by quantum chromodynamics (QCD). The strength of the interaction is parameterised by the strong coupling constant and is modified by the gauge colour charge of the particle. The strong force acts between quarks and, unlike all other forces, does not diminish in strength with increasing distance between pairs of quarks.
The colour charge is analogous to electromagnetic charge but comes in three types: positive and negative redness, greenness, and blueness. These are just names and are not related to actual colours. The force that connects positive and negative colour charges is called the strong nuclear force. The strong nuclear force is the most powerful force involved in holding matter together. It is much stronger than the three other fundamental forces: gravity, electromagnetism, and the weak nuclear force.
The strong force also acts between protons and neutrons in an atomic nucleus, in the same way that simple chemicals are held together by the electric force. For example, a nucleus such as helium, which has two positively charged protons, is stable because the strong force overcomes the electromagnetic forces.

Gluons are force-carrying particles that act as the glue binding baryonic matter together
Gluons are indeed force-carrying particles that act as the glue binding baryonic matter together. They are the carriers of the strong force, one of the four fundamental forces of nature. This strong force is the most powerful force involved in holding matter together, much stronger than gravity, electromagnetism, and weak nuclear forces.
Gluons are massless elementary particles that mediate strong interactions between quarks, acting as the exchange particle for the interaction. Quarks and gluons are the only fundamental particles that carry non-vanishing colour charge, and hence they participate in strong interactions only with each other. The strong force is the expression of the gluon interaction with other quark and gluon particles.
The colour charge is analogous to electromagnetic charge, but it comes in three types: positive and negative redness, greenness, and blueness. These so-called colour charges are just names and are not related to actual colours. The force that connects positive and negative colour charges is called the strong nuclear force. The strength of the strong force is parameterised by the strong coupling constant, and this strength is modified by the gauge colour charge of the particle. Unlike other forces, the strong force does not diminish in strength with increasing distance between pairs of quarks.
The strong force acts between protons and neutrons in an atomic nucleus, much like how simple chemicals are held together by the electric force. A nucleus such as helium, with two positively charged protons, is stable because the strong force overcomes the electromagnetic force. The strong force also acts indirectly, transmitting gluons that form part of virtual mesons, which in turn transmit the force between nucleons that holds the nucleus together.

Gluons carry the colour charge of the strong interaction
Gluons are the carriers of the strong force, one of the four fundamental forces. They are massless particles with a quantum spin of 1 and are referred to as 'gauge bosons'. Gluons play an important role in the elementary strong interactions between quarks and other gluons, described by quantum chromodynamics (QCD).
Quarks and gluons are the only fundamental particles that carry non-vanishing colour charge and hence participate in strong interactions only with each other. Gluons carry both colour and anticolour, with each gluon having a combination of two colour charges. There are nine possible combinations of colour and anticolour in gluons. Quarks, on the other hand, carry three types of colour charge, while antiquarks carry three types of anticolour.
The colour charge of quarks and gluons is related to the particles' strong interactions in the theory of QCD. Like electric charge, it determines how quarks and gluons interact through the strong force. However, rather than there being only positive and negative charges, there are three "charges", commonly called red, green, and blue, and three corresponding "anticolours". All three colours mixed together, or a combination of a colour and its anticolour, is "colourless" or "white" and has a net colour charge of zero.
The strong force is the expression of the gluon interaction with other quark and gluon particles. Gluon-gluon interactions constrain colour fields to string-like objects called "flux tubes", which exert a constant force when stretched. Due to this force, quarks are confined within composite particles called hadrons.

Gluons are massless gauge bosons
Gluons are the carriers of the strong force, one of the four fundamental forces of nature. They are force-carrying particles that bind baryonic matter together. Gluons are electrically neutral and are the only fundamental particles that carry non-vanishing colour charge. Quarks and gluons carry these colour charges, which are not related to actual colours. The strong force is the expression of the gluon interaction with other quark and gluon particles.
In particle physics, a gauge boson is a bosonic elementary particle that acts as the force carrier for elementary fermions. Gluons are massless gauge bosons. The other massless gauge boson is the photon, which carries the electromagnetic force. Gluons, on the other hand, carry the strong force. All known gauge bosons have a spin of 1 and are therefore vector bosons. Gluons are confined within hadrons and cannot be observed as free particles. Hence, their presumed lack of rest mass cannot be confirmed by any feasible experiment.
The strong force is the strongest of the four fundamental forces. At a distance of 10^-15 m, its strength is about 100 times that of the electromagnetic force, 106 times that of the weak force, and 10^38 times that of gravitation. The strong force acts between quarks and, unlike all other forces, does not diminish in strength with increasing distance between quark pairs. The strong force is responsible for holding matter together. It is much stronger than gravity, electromagnetism, and the weak nuclear forces.
The interaction between quarks and gluons is responsible for almost all the perceived mass of protons and neutrons and is therefore where we get our mass. Gluons are studied at DOE accelerator facilities like the Continuous Electron Beam Accelerator Facility (CEBAF) at the Thomas Jefferson National Accelerator Facility.

Gluons were first detected in 1979
Gluons are the carriers of the strong force, one of the four fundamental forces of nature. They are electrically neutral and are the glue that binds baryonic matter together. Quarks and gluons are the only fundamental particles that carry non-vanishing color charge and hence they participate in strong interactions only with each other. The strong force is the expression of the gluon interaction with other quark and gluon particles.
Gluons First Detected in 1979
In 1979, experiments at the DESY laboratory in Germany provided the first direct proof of the existence of gluons. This discovery was a milestone in the history of particle physics as it helped establish the theory of the strong force, known as quantum chromodynamics. The results followed from an idea that struck theorist John Ellis while walking in CERN's corridors in 1976. Ellis and theorists Mary Gaillard and Graham Ross then wrote a paper titled "Search for Gluons in e+-e– Annihilation" in which they described a calculation of the process and showed how the PETRA collider at DESY and the PEP collider at SLAC would be able to observe it.
At the International Neutrino Conference in Bergen, Norway, on 18 June 1979, researchers presented a three-jet collision event that had just been detected by the TASSO experiment at PETRA. Analysis of the three-jet events showed that two of the three particle jets were produced by a quark-antiquark pair, and the third was generated by a gluon. Shortly afterward, similar three-jet event topologies were announced by JADE, MARK J, and PLUTO, the other groups working at PETRA. All four collaborations presented their data at the Lepton-Photon Symposium at Fermilab in Chicago in August 1979.
The discovery of gluons was significant as it provided experimental proof of the existence of the particle that transmits the strong force. This helped to establish the theory of quantum chromodynamics, which describes the interactions of quarks and gluons.

Frequently asked questions
Gluons are massless elementary particles that mediate the strong interaction between quarks. They are the building blocks of protons and neutrons, which in turn are the building blocks of atomic nuclei.
Gluons have no electric charge. However, they carry the colour charge of the strong interaction, which is different from actual colours. Quarks can have a positive or negative electric charge, but both quarks and gluons have three additional states of charge: positive and negative redness, greenness, and blueness.
The electroweak force is the unified description of two of the fundamental interactions of nature: electromagnetism and the weak interaction. At high temperatures, these two forces merge into a single electroweak force.
Gluons are not directly related to the electroweak force. However, they are similar to photons, which are force carriers for electromagnetism, one of the fundamental forces that make up the electroweak force. Gluons carry the strong force between quarks, just as photons carry the force between electrically charged particles.
