Query: Quasi-two-body decays $B \to D K^*(892) \to D K \pi$ in the perturbative
  QCD approach   We study the quasi-two-body decays $B\to D K^*(892) \to D K\pi$ by employing
the perturbative QCD approach. The two-meson distribution amplitudes
$\Phi_{K\pi}^{\text{$P$-wave}}$ are adopted to describe the final state
interactions of the kaon-pion pair in the resonance region. The resonance line
shape for the $P$-wave $K\pi$ component $K^*(892)$ in the time-like form factor
$F_{K\pi}(s)$ is parameterized by the relativistic Breit-Wigner function. For
most considered decay modes, the theoretical predictions for their branching
ratios are consistent with currently available experimental measurements within
errors. We also disscuss some ratios of the branching fractions of the
concerned decay processes. More precise data from LHCb and Belle-II are
expected to test our predictions.
