Abstract
We calculate next-to-next-to-leading order soft-gluon corrections to top quark total
and differential cross sections in hadron colliders. We increase the accuracy of our previous
estimates by including additional subleading terms, including next-to-next-to-next-toleading-
logarithmic and some virtual terms. We show that the kinematics dependence of
the cross section vanishes near threshold and is reduced away from it. The factorization
and renormalization scale dependence of the cross section is also greatly reduced. We
present results for the top quark total cross sections and transverse momentum distributions
at the Tevatron and the LHC.
