Charmless non-leptonic B_s decays to PP, PV and VV final states in the pQCD approach

Abstract

We calculate the CP-averaged branching ratios and CP-violating asymmetries of a number of two-body charmless hadronic decays $\overline{B_s^0}\to PP,PV,VV$ in the perturbative QCD (pQCD) approach to leading order in ${\alpha }_s$ (here $P$ and $V$ denote light pseudoscalar and vector mesons, respectively). The mixing-induced CP violation parameters are also calculated for these decays. We also predict the polarization fractions of $B_s\to VV$ decays and find that the transverse polarizations are enhanced in some penguin dominated decays such as $\overline{B_s^0}\to K^{\ast }\overline{K^{\ast }}$, $K^{\ast }\rho$. Some of the predictions worked out here can already be confronted with the recently available data from the CDF collaboration on the branching ratios for the decays $\overline{B_s^0}\to K^{+}{\pi }^{-}$, $\overline{B_s^0}\to K^{+}{K}^{-}$ and the CP-asymmetry in the decay $\overline{B_s^0}\to K^{+}{\pi }^{-}$, and are found to be in agreement within the current errors. A large number of predictions for the branching ratios, CP-asymmetries and vector-meson polarizations in $\overline{B_s^0}$ decays, presented in this paper and compared with the already existing results in other theoretical frameworks, will be put to stringent experimental tests in forthcoming experiments at Fermilab, LHC and Super B-factories.
