Weak interaction corrections to hadronic top quark pair production

Abstract

In this paper we determine the weak-interaction corrections of order ${\alpha }_s^2\alpha$ to hadronic top-quark pair production. First we compute the one-loop weak corrections to $t\bar{t}$ production due to gluon fusion and the order ${\alpha }_s^2\alpha$ corrections to $t\bar{t}$ production due to (anti)quark gluon scattering in the Standard Model. With our previous result this yields the complete corrections of order ${\alpha }_s^2\alpha$ to $gg$, $q\bar{q}$, $qg$, and $\bar{q}g$ induced hadronic $t\bar{t}$ production with $t$ and $\bar{t}$ polarizations and spin-correlations fully taken into account. For the Tevatron and the LHC we determine the weak contributions to the transverse top-momentum and to the $t\bar{t}$ invariant mass distributions. At the LHC these corrections can be of the order of 10 percent compared with the leading-order results, for large $p_T$ and $\mtt$, respectively. Apart from parity-even $t\bar{t}$ spin correlations we analyze also parity-violating double and single spin asymmetries, and show how they are related if CP invariance holds. For $t$ (and $\bar{t}$) quarks which decay semileptonically, we compute a resulting charged-lepton forward-backward asymmetry $A_{PV}$ with respect to the $t$ ($\bar{t}$) direction, which is of the order of one percent at the LHC for suitable invariant-mass cuts.
