Lorentz-Dirac Deformation in High-Energy Physics

Here we are interested in using Dirac’s picture of Lorentz deformation to explain how hadrons appear to observers in Lorentz frames which are not at rest with respect to the hadron. We examine whether this picture is consistent with what we observe in high-energy laboratories. We are particularly interested in studying the nucleon form factors, Feynman’s parton picture, and the hadron jet phenomenon. We concluded previously that hadrons are quantum bound states of quarks having a localized probability distribution. If the proton consists of quarks distributed within a finite space-time region, the virtual photon from high energy experiments will interact with quarks which carry fractional charges. The scattering amplitude will depend on the way in which quarks are distributed within the proton. We discuss the meaning of and calculate the proton form factor. In conjunction with high energy inelastic scattering, we discuss the process of scaling. Feynman observed that a fast-moving hadron can be regarded as a collection of many partons whose properties do not appear to be identical to those of quarks. We discuss how quarks and partons can appear different to an observer in a different Lorentz frame. Additionally, we discuss the jet phenomenon which occurs in high energy processes.
