Probing the chromoelectric and chromomagnetic dipole moments of the top quark at hadronic colliders

We study the effects of the anomalous chromoelectric and chromomagnetic dipole moments of the top quark on top-pair production, on top-pair plus one jet production, and on their ratios, as well as their dependence on the transverse momenta of the top quark and the jet. We also construct CP-odd and (T) over cap-odd observables to probe the dispersive part of the chromoelectric form factor of the top quark, and compare their sensitivities in both top-pair and top-pair plus one jet production.
