This is the proposed scenario:

We have an individual proton held in place by a contrived magnetic field which remains constant. Now, we fire photons and that spot where the proton is forced by the field and measure where the photon ends up to see if it collided with the proton. (Assuming we had such precision). The question is, could the photon fly through the proton? Could the photon go between the quarks? Or would it have to collide with something (proton/quark/gluon) so long as it flew within the diameter of the proton?

My best guess would be that it would not be a collision or going right through. The wave of the photon would be influenced by the energy and the parts that make up the the proton. They would change each other. The 'same' photon may come though, or, its interaction with the system of the proton may absorb its energy partially or wholely and either leave the photon a lower frequency or perhaps even spawn another photon althogether as a part of its interraction.
