摘要：

Recently, new efficient rules have been derived for computing one-loop amplitudes in pure gauge theories, using the technology of four-dimensional heterotic strings. We advocate the Schottky parametrization as a means to generalize these methods to multiloop level. An explicit expression is given for the N-gluon h-loop amplitude.
