摘要

I present results for top-quark double-differential distributions in transverse momentum and rapidity. Second- and third-order soft-gluon corrections derived from next-to-next-to-leading-logarithm resummation are added to the complete next-to-leading-order result, and the combination is denoted as approximate N 3 LO . The corrections are large and they reduce theoretical uncertainties. The theoretical results are in good agreement with recent data from the LHC.
