Background/Objectives: The primary objective is to investigate a new theoreticalmodel approach about fundamental particles. Especially the electron and positron is con-sidered. The model utilizing the concept of energy density limits and find an acceptableinterpretation of a speed of light reference frame. Due to it’s consistent nature this enableus to implement these limits without breaking Lorentz’s invariance. This new model em-ploys mass-less current loops at the speed of light, to construct a candidate for a stable,self-contained system, which can be perceived as either an electron or positron, dependingon its configuration.Methods: This is a pure theoretical work where all figures was generated by LaTeXconstructs to illustrate the concepts. However there are referenced measurement results thatare important for the discussion. The mathematics is on a basic level, although the paperis dense with deductions and formulas. Only calculus and general mathematical maturity isneeded as well as knowledge about special relativity, electromagnetism and some basic atomand particle physics.Results: We evaluate the resultant angular momentum and derive a formula that alignswith Bohr’s renowned assumption about angular momentum in his atomic model. Thismethod not only provides insights into the enigmatic number 137 in physics but also suggestsa potential discrepancy between the masses of the electron and positron, with a relativeerror of 10 ppm in the measurement. This difference is too subtle for existing measurementtechniques.Conclusions: The main result in this paper are a model that basis its approach using theelectromagnetic theory and deduces stable constellations, that resembles particles, withinthis model. This theory does introduce the controversial prediction that the particle andantiparticle mass differ using a deduction of a formula for the mass. It is also quite possible aswe quantize the difference, that this prediction can be clarified by forthcoming measurementprojects. Also we deduced a couple of soundness feature of the model, such as deriving theBohr’s condition for angular momentum in his atomic model and explain how this can beused to deduce the actual measured angular momentum. Also the invariance of angularmomentum and charge is proven as a result of the model.
