When one speaks of high energy particles like electrons and protons, it would not be correct to view them just as massive particles. It must be remembered that they have an electro-magnetic field attached to them and which propagates along with them as they move. From the perspective of Quantum Electrodynamics, they emit virtual photons and other particles which contributes to the field around them.

When we speak of an electron or proton there is some uncertainty about what we are referring to. When they interact with something, there is usually a lot of uncertainty about what actually happened.

We are again limited by the information available to us. Our knowledge of electrons and protons is pieced together from an enormous number of experiments.
