摘要：

In this work we study the anomalous top quark-gluon couplings chromoelectric dipole moment and chromomagnetic dipole moment in a general two Higgs doublet model with CP violation. We find that this model provides an important contribution from the Y-tt Yukawa coupling that needs to be taken into account. The predictions for the chromomagnetic dipole moment and chromoelectric dipole moment obtained are -0.03 < Delta<(k)over tilde>(t) < -0.005 and vertical bar Delta<(d)over tilde>(t)vertical bar < 0.005, respectively.
