Query: An algorithm for the high-energy expansion of multi-loop diagrams to
  next-to-leading logarithmic accuracy   We present an algorithm to compute arbitrary multi-loop massive Feynman
diagrams in the region where the typical energy scale \sqrt{s} is much larger
than the typical mass scale M, i.e. s>>M^2, while various different energy and
mass parameters may be present. In this region we perform an asymptotic
expansion and, using sector decomposition, we extract the leading contributions
resulting from ultraviolet and mass singularities, which consist of large
logarithms log(s/M^2) and 1/\epsilon poles in D=4-2\epsilon dimensions. To
next-to-leading accuracy, at L loops all terms of the form \alpha^L
\epsilon^{-k} log^j(s/M^2) with j+k=2L and j+k=2L-1 are taken into account.
This algorithm permits, in particular, to compute higher-order next-to-leading
logarithmic electroweak corrections for processes involving various kinematical
invariants of the order of hundreds of GeV and masses M_W \sim M_Z \sim M_H
\sim M_t of the order of the electroweak scale, in the approximation where the
masses of the light fermions are neglected.
