摘　　要：We describe predictions for top quark pair differential distributions at hadron colliders,by combining the next-to-next-to-leading order quantum chromodynamics calculations and next-to-leading order electroweak corrections with double resummation at the next-to-next-to-leading logarithmic accuracy of threshold logarithms and small-mass logarithms.To the best of our knowledge,this is the first study to present such a combination,which incorporates all known perturbative information.Numerical results are presented for the invariant-mass distribution,transverse-momentum distribution,and rapidity distributions.
