چکیده    We make a complete one loop calculation of the tbw couplings in the two higgs doublet model. we evaluate both the anomalous couplings g l and g r as well as left handed and right handed component of tbw . the computation is done in the feynman gauge using the on-shell scheme renormalization for the standard model wave functions and parameters. we first show that the relative corrections to these anomalous couplings are rather small in most regions of the parameter space. we then analyze the effects of these anomalous couplings on certain observables such as top quark polarization in single top production through t−channel as well as w ± boson helicity fractions in top decay.
