# The Unpublished Feynman Diagram IIc

@article{Consa2020TheUF, title={The Unpublished Feynman Diagram IIc}, author={Oliver Consa}, journal={arXiv: History and Philosophy of Physics}, year={2020} }

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…

The new measurement has an uncertainty that is about six times smaller, and it shifts the values by 1.7 standard deviations, so the lowest quantum levels of the spin and cyclotron motion are resolved, and the cycle frequencies as well as spin frequencies are determined using quantum jump spectroscopy.
