High-precision calculation of the 4-loop contribution to the electron g-2 in QED
I have evaluated up to 1100 digits of precision the contribution of the 891 4-loop Feynman diagrams contributing to the electron g-2 in QED. The total mass-independent 4-loop contribution is ae=−1.912245764926445574152647167439830054060873390658725345…(απ)4. I have fit a semi-analytical expression t...
