Query: Theoretical results for top-quark cross sections and distributions   I present new results and updates for total cross sections and differential
distributions in top-antitop pair and single-top production. Soft-gluon
corrections are added to exact fixed-order results to provide the best
predictions at approximate N$^3$LO for $t{\bar t}$ production and approximate
NNLO for single-top production. Total cross sections and top-quark
transverse-momentum and rapidity distributions are presented and compared with
data at LHC and Tevatron energies. The cusp anomalous dimension at three and
higher loops is also discussed.
