The study of charmless hadronic $B_s$ decays

Understand

The perturbative QCD approach has achieved great success in the study of hadronic B decays.

• Utilizing the constrained parameters in these well measured decay channels, we study most of the possible charmless $B_s \to PP$, $PV$ and $VV$ decay channels in the perturbative QCD approach.
• In addition to the branching ratios and CP asymmetries, we also give predictions to the polarization fractions of the vector meson final states.
• The size of SU(3) breaking effect is also discussed.
