Two-loop planar corrections to heavy-quark pair production in the quark-antiquark channel
We evaluate the planar two-loop QCD diagrams contributing to the leading color coefficient of the heavy-quark pair production cross section, in the quark-antiquark annihilation channel. We obtain the leading color coefficient in an analytic form, in terms of oneand two-dimensional harmonic polylogarithms of maximal weight 4. The result is valid for arbitrary values of the Mandelstam invariants ...
متن کاملTwo-loop fermionic corrections to heavy-quark pair production: the quark-antiquark channel
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 furth...
متن کاملFermionic Corrections to the Heavy-Quark Pair Production in the Quark-Antiquark Channel
The top quark is the heaviest fermion of the Standard Model. Since its discovery at the Fermilab Tevatron [1], its mass has been measured to within a few percent, while its production cross section and couplings are currently known with larger uncertainty. With the large number of top quarks expected to be produced at the LHC, the study of its properties will become precision physics. To interp...
متن کاملTwo-Loop Leading Color Corrections to Heavy-Quark Pair Production in the Gluon Fusion Channel
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 th...
متن کاملElectroweak corrections to top-quark pair production in quark–antiquark annihilation
Top-quark physics plays an important rôle at hadron colliders such as the Tevatron at Fermilab or the LHC at CERN. Given the planned precision at these colliders, precise theoretical predictions are required. In this paper we present the complete electroweak corrections to QCD-induced top-quark pair production in quark–antiquark annihilation. In particular we provide compact analytic expression...
