Mixed QCD and weak corrections to top quark pair production at hadron colliders
نویسنده
چکیده
The order αs α mixed QCD and weak corrections to top quark pair production by quark antiquark annihilation are computed, keeping the full dependence on the t and t̄ spins. We determine the contributions to the cross section and to single and double top spin asymmetries at the parton level. These results are necessary ingredients for precise standard model predictions of top quark observables, in particular of top spin-induced parity-violating angular correlations and asymmetries at hadron colliders.

Electroweak 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...
متن کاملWeak Interactions in Top-Quark Pair Production at Hadron Colliders: An Update
Weak corrections for top-quark pair production at hadron colliders are revisited. Predictions for collider energies of 8 TeV, adopted to the present LHC run, and for 14 TeV, presumably relevant for the next round of LHC experiments, are presented. Kinematic regions with large momentum transfer are identified, where the corrections become large and may lead to strong distortions of differential ...
متن کاملLeading Electroweak Corrections to the Production of Heavy Top Quarks at Hadron Colliders
We calculate the electroweak corrections of the order O( 2 t v2 ) to the QCD production of tt̄ pairs via qq̄ → tt̄ at hadron colliders and show that these corrections to the total production rate are small. This correction can be characterized as increasing the cross section most near the threshold region, where top quark signals are important, while the corrections become negative at higher tt̄ en...
متن کاملNLO Supersymmetric QCD Corrections to tt̄h Associated Production at Hadron Colliders
We calculate NLO QCD corrections to the lightest neutral Higgs boson production associated with top quark pair at hadron colliders in the minimal supersymmetric standard model(MSSM). Our calculation shows that the total QCD correction significantly reduces its dependence on the renormalization/factorization scale. The relative correction from the SUSY QCD part approaches to be a constant, if ei...
متن کاملTHE FLORIDA STATE UNIVERSITY COLLEGE OF ARTS AND SCIENCES NEXT-TO-LEADING-ORDER CORRECTIONS TO WEAK BOSON PRODUCTION WITH A MASSIVE QUARK JET PAIR AT HADRON COLLIDERS By FERNANDO FEBRES CORDERO
We present the calculation of Next-to-Leading-Order Quantum Chromo Dynamics corrections for the production of a W or Z weak boson associated with a bottom anti-bottom quark pair at hadron colliders (pp̄, pp → W/Z bb̄), including the effects of a non-zero bottomquark mass. We find a considerable reduction of the renormalization and factorization scale dependence of our results with respect to Lead...
