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…
Next-to-leading order corrections to e^+ e^- \to four jets
A. Signer
I present a general purpose Monte Carlo program for calculating the next-to-leading order corrections to arbitrary four-jet quantities in electron-positron annihilation. In the cur…
