Abstract

The ``Comment'' presented in hep-ph/0303188 is not even wrong: Fujikawa and Shrock miss entirely the crucial point that the observable quantity associated with the neutrino charge radius (NCR) is not given by the (off-shell) one-loop vertex γ*νν dictated by the Feynman diagrams in the Rξ gauge-fixing scheme.
