A Photon-Based Vector Particle Model for Proton and Neutron Masses

This work presents a simplified geometric model for the proton-to-electron mass ratio (mp/me), achieving a remarkable precision of seven significant figures (mp/me ≈ 1836.1521964, relative error −2.6 × 10−7) matching CODATA’s 1836.15267343. Building on T.N. Lockyer’s Vector Particle Physics (2000), the model eliminates an ad hoc QED-inspired correction, improving precision from six to seven significant figures in double-precision arithmetic. Rounding errors do not allow us to verify whether this model predicts a better outcome. The neutron-to-electron mass ratio (mn/me ≈ 1838.68982960, error 3.35 × 10−6) achieves six significant figures, consistent with the model’s structure.
