The best evidence for bosons (force-carrying particles) is to be found in the cloud chambers associated with colliders. The standard model of physics predicts the existence of families of particles and the results from the collision of high energy protons in colliders like the Large Hadron Collider back up the theory. Gluons are not directly detected, but certain events in the cloud chamber indicate something like a gluon is involved in the events. The Higgs boson which was predicted by the standard model has recently been verified in the LHC. A book, the Particle at The End of the Universe by Sean Carroll is a fabulous reference for answering your question. Sean is one of many modern writers who are making physics more and more accessible to non-mathematicians.
