Query: Fock States of Flavor Neutrinos are Unphysical   It is shown that it is possible to construct an infinity of Fock spaces of
flavor neutrinos depending on arbitrary unphysical mass parameters, in
agreement with the theory of Blasone and Vitiello in the version proposed by
Fujii, Habe and Yabuki. However, we show that these flavor neutrino Fock spaces
are clever mathematical constructs without physical relevance, because the
hypothesis that neutrinos produced or detected in charged-current weak
interaction processes are described by flavor neutrino Fock states implies that
measurable quantities depend on the arbitrary unphysical flavor neutrino mass
parameters.
