Two-loop fermionic corrections to heavy-quark pair production: the quark-antiquark channel


Bonciani, R; Ferroglia, A; Gehrmann, T; Maître, D; Studerus, C (2008). Two-loop fermionic corrections to heavy-quark pair production: the quark-antiquark channel. Journal of High Energy Physics, (07):129.

Abstract

We evaluate the fermionic two-loop QCD corrections to the heavy-quark pair production process in the quark-antiquark channel. We obtain analytic results which are valid for any value of the Mandelstam invariants s and t, and of the heavy quark mass m. Our findings confirm previous results for the analytic evaluation in the small-mass limit and numerical results for the exact amplitude. We furthermore provide the expansion of the two-loop amplitude at the production threshold s gtrsim 4m2.
