Top quark chromoelectric and chromomagnetic dipole moments in a two Higgs doublet model withCPviolation

Abstract

In this work we study the anomalous top quark-gluon couplings Chromoelectric Dipole Moment (CEDM) and Chromomagnetic Dipole Moment (CMDM) in a general THDM 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 CMDM and CEDM obtained are $-0.03<\Delta\tilde{k} < 0.005}$ and $|\Delta \tilde{d}| < 0.005$, respectively.
