Query: The role of $f_0(1710)$ in the $\phi \omega$ threshold peak of $J/\Psi
  \to \gamma \phi \omega$   We study the process $J/\Psi \to \gamma \phi \omega$, measured by the BES
experiment, where a neat peak close to the $\phi \omega$ threshold is observed
and is associated to a scalar meson resonance around 1800 MeV. We make the
observation that a scalar resonance coupling to $\phi \omega$ unavoidably
couples strongly to $K \bar K$, but no trace of a peak is seen in the $K \bar
K$ spectrum of the $J/\Psi \to \gamma K \bar K$ at this energy. This serves us
to rule out the interpretation of the observed peak as a signal of a new
resonance. After this is done, a thorough study is performed on the production
of a pair of vector mesons and how its interaction leads necessarily to a peak
in the $J/\Psi \to \gamma \phi \omega$ reaction close to the $\phi \omega$
threshold, due to the dynamical generation of the $f_0(1710)$ resonance by the
vector-vector interaction. We then show that both the shape obtained for the
$\phi \omega$ mass distribution, as well as the strength are naturally
reproduced by this mechanism. The work also explains why the $\phi\omega$ peak
is observed in the BES experiment and not in other reactions, like $B^\pm\to
K^\pm \phi\omega$ of Belle.
