Query: Anatomy of $B_s \to PV $ decays and effects of next-to-leading order
  contributions in the perturbative QCD factorization approach   In this paper, we will make systematic calculations for the branching ratios
and the CP-violating asymmetries of the twenty one $\bar{B}^0_s \to PV $ decays
by employing the perturbative QCD (PQCD) factorization approach. Besides the
full leading-order (LO) contributions, all currently known next-to-leading
order (NLO) contributions are taken into account. We found numerically that:
(a) the NLO contributions can provide $\sim 40\%$ enhancement to the LO PQCD
predictions for ${\cal B}(\bar{B}_s^0 \to K^0 \bar{K}^{*0})$ and $ {\cal
B}(\bar{B}_s^0 \to K^{\pm}K^{*\mp})$, or a $\sim 37\% $ reduction to $
\calb(\bar{B}_s^0 \to \pi^{-} K^{*+})$, and we confirmed that the inclusion of
the known NLO contributions can improve significantly the agreement between the
theory and those currently available experimental measurements, (b) the total
effects on the PQCD predictions for the relevant $B\to P$ transition form
factors after the inclusion of the NLO twist-2 and twist-3 contributions is
generally small in magnitude: less than $ 10\%$ enhancement respect to the
leading order result, (c) for the "tree" dominated decay $\bar B_s^0\to K^+
\rho^- $ and the "color-suppressed-tree" decay $\bar B_s^0\to \pi^0 K^{*0}$,
the big difference between the PQCD predictions for their branching ratios are
induced by different topological structure and by interference effects among
the decay amplitude ${\cal A}_{T,C}$ and ${\cal A}_P$: constructive for the
first decay but destructive for the second one, and (d) for $\bar{B}_s^0 \to
V(\eta, \etar)$ decays, the complex pattern of the PQCD predictions for their
branching ratios can be understood by rather different topological structures
and the interference effects between the decay amplitude $\cala(V\eta_q)$ and
$\cala(V\eta_s)$ due to the $\eta-\etar$ mixing.
