Abstract
A bound on the CPT-odd four-vector coefficient [Formula: see text] that appears in Higgs sector of the minimal Standard Model Extended (mSME) is presented. The analysis is based on the contributions arising from the sector in question to the anomalous magnetic dipole moment (AMDM) for leptons calculated at the one-loop level, for which an analytical expression is obtained. The largest contribution of this Lorentz violating coefficient is on the lightest lepton, which results as a consequence of a strong nondecoupling effect. By using the experimental uncertainty of the electron AMDM we predict that [Formula: see text].
