New Methods for the Calculation of Multi-Loop Amplitudes
arXiv:0810.3620
Abstract
We present a brief review of current methods for the calculation of multi-loop amplitudes including recent developments. As an example we present the calculation of the second moment of the heavy quark current correlator and the extraction of the values of the charm and bottom quark masses using the results of this calculation.
