摘要：

We compute the critical exponent eta, which relates to the anomalous dimension of the electron, in the large N(f) expansion of QED at leading order in arbitrary dimensions in the Landau gauge. Subsequently we show that transcendental numbers will arise at fifth order and beyond in the corresponding renormalization group function in four dimensions.
