The Fine-Structure Constant in the Bivector Standard Model

The geometrical view of the electron as a spinning bivector leads to the partitioning of the electron’s energy into internal and external. The reduced Compton wavelength, λ¯C, is taken as the radius of the inertial ring (a disc), while re characterizes the EM coupling scale. Within this picture, the fine-structure constant emerges as the structural ratio α=re/λ¯C. We make the partitioning explicit, derive simple ratios among moments of inertia and stored energies, and compare the Bivector Standard Model with the Standard model.
