Tau Magnetic Anomaly without QED-QCD

The standard theoretical determination of the tau magnetic anomaly is carried out with techniques analogous to those used for the muon, with a greater contribution from hadronic terms arising from QCD. The mean lifetime of the muon is much longer than that of the tau, therefore precise experimental measurements of the magnetic anomaly of the latter are difficult and not yet useful for comparison with theoretically determined values. For this reason, the theoretical value calculated in this work will be compared only with the theoretical value determined by the Standard Model. The document follows the same framework and development phases as those used in the muon case. The only difference is constituted by the tau mass, which produces an increase of two internal levels and the modification of the immediately adjacent and external one. This similarity of the analytical approach allows us to focus attention only on the distinctive parts, summarizing the other sections and referring, for a more detailed analysis, to the previous works concerning the magnetic anomaly of the electron (viXra 2505. 0128) and, more specifically, of the muon (viXra 2505. 0135). The structure of the tau contains that of the muon, which in turn contains that of the electron with its corresponding mass, total charge, and charge source. Relative errors of the order of 10^-8 on the total mass and of the order of 10^-8 on the magnetic anomaly are achieved with respect to the standard theoretical value.
