How did scientist discover the gluon?
Positive charged protons repel each other but the gluon over comes the repelling force.
Is the gluon a mathematic proof or a measurable substance?

The first (and still the best) experimental evidence of gluons was in the form of three-jet events in particle accelerator experiments, the first of which was observed in 1979. Jets are usually produced by the hadronization of quarks; and since quarks are produced in pairs, the third jet must represent an additional particle. Quantum chromodynamics suggests that this extra particle is a high-energy gluon, and this interpretation also explains other features present in three-jet events.

Gluons do not interact directly with protons or other hadrons. Instead, they mediate strong-force interactions between quarks, binding quarks together to form hadrons.

Free gluons have not yet been detected, but high-energy particle collisions have produced what is believed to be a quark-gluon plasma. The heat and pressure from the collision (conditions similar to those a few microseconds after the Big Bang) "melt" the colliding hadrons into their quark and gluon components. As the plasma expands and cools, the quarks and gluons recombine, forming hadrons which can be observed directly. However, the decay products associated with a QGP are hard to distinguish from decay from other causes, so further investigation is needed to confirm that this really is a QGP. Otherwise, the evidence for gluons is theoretical, but there are no strong competing theories to suggest that something other than gluons may be responsible for the observed phenomena.
