Analytical evaluation of certain on-shell two-loop three-point diagrams
A. I. Davydychev, V. A. Smirnov
An analytical approach is applied to the calculation of some dimensionally-regulated two-loop vertex diagrams with essential on-shell singularities. Such diagrams are important for…

Heavy-quarkonium creation and annihilation with O(alpha_s^3 ln(alpha_s)) accuracy
Bernd A. Kniehl, Alexander A. Penin, Vladimir A. Smirnov +1
We calculate the O(alpha_s^3 ln(alpha_s)) contributions to the heavy-quarkonium production and annihilation rates. Our result sheds new light on the structure of the high-order per…

Analytical Evaluation of Double Boxes
V. A. Smirnov
Recent results on the analytical evaluation of double-box Feynman integrals and the corresponding methods of evaluation are briefly reviewed.
