We compute the one-loop contribution for the leptonic Z width, anomalous magnetic, weak-magnetic, electric and weak dipole moments of leptons in order to extract bounds on the energy scale of these effective interactions.2213-2221engArtigo10.1088/0954-3899/24/12/005WOS:000077509200005Acesso restrito
