+====== TTP02-13 Two-loop amplitudes with nested sums: Fermionic contributions to e+e- --> q qbar g ======
+   <hidden TTP02-13  Two-loop amplitudes with nested sums: Fermionic contributions to e+e- --> q qbar g > We present the calculation of the $\nf$-contributions to the two-loop
+ amplitude for $e^+e^-\to q \qb g$ and give results for the full one-loop
+ amplitude to order $\eps^2$ in the dimensional regularization parameter.
+ Our results agree with those recently obtained by Garland et al..
+ The calculation makes extensive use of an efficient method based on
+ nested sums to calculate two-loop integrals with arbitrary powers
+ of the propagators.  The use of nested sums leads in a natural way to
+ multiple polylogarithms with simple arguments, which allow a
+ straightforward analytic continuation.
