  Constraints on the non-standard top-gluon couplings composed of the
chromomagnetic- and chromoelectric-dipole moments of the top quark are updated
by combining the latest data of top-pair productions from the Tevatron, 7-TeV
LHC, and 8-TeV LHC. We find that adding the recent 8-TeV data to the analysis
is effective to get a stronger constraint on the chromoelectric-dipole moment
than the one from the Tevatron and 7-TeV LHC alone. We also discuss how those
constraints on the non-standard couplings could be further improved when 14-TeV
LHC results become available in the near future.
