An approach to the origin of the nonuniversal Lorentz symmetry perturbations

This work shows that the electromagnetic field impedes the motion of particles bearing electric charges. This implies that, in general, particle fields themselves possess unique maximal attainable speeds because of the effect of interactions with the surrounding force fields. This result can be identified with the particle-dependent maximal attainable speed that is studied under Lorentz-Invariance-Violation (LIV) theories within the Effective Field Theory (EFT) framework. That said, it is finally discussed how the conclusions made in this study can be beneficial to the recent work that incorporates nonuniversal Lorentz symmetry perturbations. Throughout this work, the use of basic real analysis and algebra is employed to formulate key arguments.
