Query: Probing top-quark chromomagnetic dipole moment at next-to-leading order
  in QCD   We present predictions at NLO accuracy in QCD for top-quark pair production
induced by an anomalous chromomagnetic dipole moment of the top quark. Our
results are obtained for total as well as fully differential cross sections,
including matching to parton shower simulations. This process is expected to
provide the most stringent direct limits on top-quark chromomagnetic dipole
moment. We find that NLO corrections increase the contribution from the dipole
moment by about 50\% at the LHC, and significantly reduce the renormalization
and factorization scale dependence. Using the NLO prediction, we update the
current limit from the Tevatron and the LHC measurements. Apart from total
cross section, we also study other observables relevant for LHC phenomenology.
