Bonciani, R; Ferroglia, A; Gehrmann, T; von Manteuffel, A; Studerus, C (2011). Two-loop leading color corrections to heavy-quark pair production in the gluon fusion channel. Journal of High Energy Physics, (1):102.
We evaluate the two-loop QCD diagrams contributing to the leading color coefficient of the heavy-quark pair production cross section in the gluon fusion channel. We obtain an analytic expression, which is valid for any value of the Mandelstam invariants s and t and of the heavy-quark mass m. Our findings agree with previous analytic results in the small-mass limit and with recent results for the coefficients of the IR poles.
