Searching for the Feynman diagram IIc

TL;DR

This paper investigates the unpublished and unverified Feynman diagram IIc in QED, which is crucial for the electron g-factor calculation, aiming to find published recalculations for independent validation.

Contribution

The paper initiates a search for published recalculations of the critical Feynman diagram IIc to enable independent verification of fundamental QED predictions.

Findings

No published recalculation of diagram IIc found

Highlights the importance of independent validation in QED

Calls for further research to verify the diagram's calculation

Abstract

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. Although it is hard to believe, neither the original calculation nor the subsequent correction was ever published. Therefore, the entire prestige of QED and the Standard Model depends on the calculation of a single Feynman diagram (IIc) that has never been published and cannot be independently verified. In this article we begin the search for any published recalculation of this Feynman diagram IIc that allows us to independently validate the theoretical calculation.
