Heavy quark pair production in gluon fusion at next-to-next-to-leading order: One-loop squared contributions
arXiv:0809.3980 · doi:10.1103/PhysRevD.78.094013
Abstract
We calculate the next-to-next-to-leading order one-loop squared corrections to the production of heavy-quark pairs in the gluon-gluon fusion process. Together with the previously derived results on the production channel the results of this paper complete the calculation of the one-loop squared contributions of the next-to-next-to-leading order radiative QCD corrections to the hadroproduction of heavy flavors. Our results, with the full mass dependence retained, are presented in a closed and very compact form, in dimensional regularization.
