The Unpublished Feynman Diagram IIc

TL;DR

This paper discusses the significance of an unpublished Feynman diagram (IIc) in QED, highlighting its impact on the theory's credibility due to lack of independent verification.

Contribution

It uncovers the historical and scientific importance of the unpublished Feynman diagram IIc in quantum electrodynamics.

Findings

The original Feynman diagram IIc was never published.

A correction to the diagram was identified but not published.

The unverified diagram affects the credibility of QED calculations.

Abstract

Quantum Electrodynamics (QED) is considered the most accurate theory in the history of science. However, this precision is limited to a single experimental value: the anomalous magnetic moment of the electron (g-factor). The calculation of the electron g-factor was carried out in 1950 by Karplus and Kroll. Seven years later, Petermann detected and corrected a serious error in the calculation of a Feynman diagram; however, neither the original calculation nor the subsequent correction was ever published.Therefore, the entire prestige of QED depends on the calculation of a single Feynman diagram (IIc) that has never been published and cannot be independently verified.
