What are gluons and what is their function?
Gluons are the exchange particles for the color force between quarks, analogous to the exchange of photons in the electromagnetic force between two charged particles. The gluon can be considered to be the fundamental exchange particle underlying the strong interaction between protons and neutrons in a nucleus.
Do gluons have mass?
Photons, which carry the force between the electrons, are there
What makes up a gluon?
In layman’s terms, they “glue” quarks together, forming hadrons such as protons and neutrons. In technical terms, gluons are vector gauge bosons that mediate strong interactions of quarks in quantum chromodynamics . Gluons themselves carry the color charge of the strong interaction.
