Query: Interaction of vector mesons with baryons and vectors in the nuclear
  medium   In this talk we present a short review of recent developments concerning the
interaction of vector mesons with baryons and with nuclei. We begin with the
hidden gauge formalism for the interaction of vector mesons, then review
results for vector baryon interaction and in particular the resonances which
appear as composite states, dynamically generated from the interaction of
vector mesons with baryons. New developments concerning the mixing of these
states with pseudoscalars and baryons are also reported. We include some
discussion on the $5/2^+$ $\Delta$ resonances around 2000 MeV, where we suggest
that the $\Delta(2000)5/2^+$ resonance, which comes in the PDG from averaging a
set of resonances appearing around 1700 MeV and another one around 2200 MeV,
corresponds indeed to two distinct resonances. We also report on a hidden charm
baryon state around 4400 MeV coming from the interaction of vector mesons and
baryons with charm, and how this state has some repercussion in the $J/\psi$
suppression in nuclei. The interaction of $K^*$ in nuclei is also reported and
suggestions are made to measure by means of the transparency ratio the huge
width in the medium that the theoretical calculations predict. The formalism is
extended to $J/\psi$ interaction with nuclei and the transparency ratio for
$J/\psi$ photoproduction in nuclei is studied and shown to be a good tool to
find possible baryon states which couple to $J/\psi N$.
