Query: Excited heavy meson decays to light vector mesons: implications for
  spectroscopy   We analyze strong decays of excited charmed and beauty mesons into a light
vector meson, exploiting the effective field theory based on heavy quark (HQ)
symmetries for heavy mesons, and on the hidden gauge symmetry to incorporate
light vector mesons. HQ symmetries allow to classify the heavy mesons in spin
doublets, and to relate decays of excited states. We build effective Lagrangian
terms governing the ${\cal H}_i \to P^{(*)} V$ modes, with ${\cal H}_i$ an
excited $s$, $p$, $d$ and $f$-wave heavy-light quark meson, $P,\,P^*$ the
lowest-lying $J^P=(0^-,\,1^-)$ heavy-light mesons, and V a light vector meson.
Predictions are provided for ratios of decay widths that are independent of the
strong couplings in the effective Lagrangian terms. A classification of the
newly observed heavy-light mesons is proposed.
