Description
The measurement of $t\bar{t}$ differential
production cross sections provides a direct test of QCD. We
present the comparison of top quark differential cross section in
$p\bar{p}$ collisions (D0) at $\sqrt{s}$=1.96
TeV as a function of the transverse momentum using various
PDFs.These cross sections are calculated in next-to-next-to-leadig
order(NNLO) in QCD using DiffTop package. Our results are in good
agreement with very recent D0 experimental data from Fermilab
Tevatron Collider. We also consider the NNLO predictions for this cross section at the LHC $\sqrt{s}$=7, 13 TeV.
