Query: Prospects for studies of $D^{*0} \to \mu^+\mu^-$ and $B_{(s)}^{*0} \to
  \mu^+\mu^-$ decays   Weak decays of the vector $D^{*0}$ and $B_{(s)}^{*0}$ mesons to the $\mumu$
final state provide novel potential to test the Standard Model of particle
physics. Such processes have extremely small branching fractions as the vector
mesons are able to decay through electromagnetic and (for the $D^{*0}$ meson)
strong interactions. Nonetheless, the production of copious quantities of these
particles in LHC collisions, and the ability to exploit experimental techniques
that can suppress background to low levels, provides good potential to reach
interesting sensitivity. The possibility to reconstruct these processes as part
of the decay chain of $B^-$ or $B_c^+$ mesons appears particularly attractive
due to the clean experimental signature of the displaced vertex. Indeed,
published LHCb data on $\Bm \to \pim\mumu$ decays already implies a stringent
limit on the branching fraction of $D^{*0} \to \mu^+\mu^-$. Estimates are made
on the achievable sensitivity to $D^{*0} \to \mu^+\mu^-$ and $B_{(s)}^{*0} \to
\mu^+\mu^-$ decays with the LHCb experiment.
