One-loop Weak Dipole Form Factors and Weak Dipole Moments of Heavy Fermions

Stefano Rigolin

The one-loop weak-magnetic and weak-electric dipole form factors of heavy fermions in a generic model are derived. Numerical predictions for the $τ$ lepton and $b$ quark Weak Anoma…

Fermion Virtual Effects in $e^{+} e^{-} - > W^{+} W^{-}$ Cross Section

A. Culatti, G. Degrassi, F. Feruglio +4

We analyse the contribution of new heavy virtual fermions to the $e^{+} e^{-} \to W^{+} W^{-}$ cross section. We find that there exists a relevant interplay between trilinear and bil…

Heavy fermions virtual effects at e^+ e^- colliders

S. Rigolin

We derive the low-energy electroweak effective lagrangian for the case of additional heavy, unmixed, sequential fermions. Present LEP1 data still allow for the presence of a new qu…
