Abstract:
We study the complete one-loop contributions to the chromagnetic dipole moment Δκ of the top quark in the Standard Model, two Higgs doublet models, topcolor assited technicolor models (TC2), 331 models and extended models with a single extra dimension. We find that the SM predicts Δκ=−0.056 and that the predictions of the other models are also consitent with the constraints imposed on Δκ by low-energy precision measurements.- 13.85.Rm
