Using Dimensional Reduction for Hadronic Collisions
Adrian Signer, Dominik Stockinger
We discuss how to apply regularization by dimensional reduction for computing hadronic cross sections at next-to-leading order. We analyze the infrared singularity structure, demon…
Combined fixed-order and effective-theory approach to sum rules
Adrian Signer
We combine the fixed-order evaluation of the sum rules with a non-relativistic effective-theory approach. The combined result for the -th moment includes all terms su…
Four-fermion production near the W pair production threshold
Martin Beneke, Pietro Falgari, Christian Schwinn +2
We perform a dedicated study of the four-fermion production process e- e+ -> mu- nubar_mu u dbar X near the W pair-production threshold in view of the importance of this process fo…
Top-Antitop Pair Production close to Threshold: Synopsis of recent NNLO Results
A. H. Hoang, M. Beneke, K. Melnikov +10
Using non-relativistic effective theories, new next-to-next-to-leading order (NNLO) QCD corrections to the total production cross section at the Linear Collider have been…
A two-loop application of the threshold expansion: the bottom quark mass from production
M. Beneke, A. Signer, V. A. Smirnov
We use the threshold expansion and non-relativistic effective theory to determine the bottom quark mass from moments of the production cross section at next-to-next-to-l…
Multi-Parton Loop Amplitudes and Next-to-Leading Order Jet Cross-Sections
Z. Bern, L. Dixon, D. A. Kosower +1
We review recent developments in the calculation of QCD loop amplitudes with several external legs, and their application to next-to-leading order jet production cross-sections. Wh…
