Threshold expansion at order alpha_s^4 for the t-tbar invariant mass distribution at hadron colliders
Valentin Ahrens, Andrea Ferroglia, Matthias Neubert +2
We calculate the leading O(alpha_s^4) contributions to the invariant mass distribution of top-quark pairs produced at the Tevatron and LHC, in the limit where the invariant mass of…

Two-loop divergences of massive scattering amplitudes in non-abelian gauge theories
Andrea Ferroglia, Matthias Neubert, Ben D. Pecjak +1
The infrared divergences of QCD scattering amplitudes can be derived from an anomalous dimension Γ, which is a matrix in color space and depends on the momenta and masses of the ex…
