Does anyone know how to calculate the coefficients for higher order (sixth and beyond) terms for the electron anomalous magnetic moment? I have a clear understanding of calculating the Schwinger term, but beyond that I cannot find anything in the usual QFT textbooks. The usual papers often quoted (eg Peterman, Levine, Kinoshita and Laporta) are short on detail. I know that the number of terms rises with the increasing order so that the higher order terms require computer algorithms to calculate these coefficients - often using Monte-Carlo integration methods, but these papers do not even show in broad terms how these calculations are phrased.
