Query: Top-quark production at the LHC: differential cross section and
  phenomenological applications   We discuss top-quark pair production at hadron colliders and review available
calculations of differential top-pair production cross section in perturbative
QCD at approximate next-to-next-to-leading order (NNLO) within the threshold
resummation formalism. These calculations are implemented into an open source
program under development. We present phenomenological studies at the LHC that
include transverse momentum and rapidity distribution of the top quarks at a
center-of-mass energy of 7 TeV. Preliminary results obtained with this program
are in very good agreement with the recent LHC measurements.
