Text: In physics, gluons are the elementary particles which are responsible for the strong nuclear force. They bind quarks together to form protons and neutrons; their electric charge is zero, their spin is 1 and they are generally assumed to have zero mass. Gluons are massless bosons which mediate the strong force between quarks. Gluons attract one another, and may form quarkless bound states called glueballs. gluon - a gauge boson that mediates strong interaction among quarks gauge boson - a particle that mediates the interaction of two elementary particles
