Fits of Weak Annihilation and Hard Spectator Scattering Corrections in $B_{u,d}\to VV$ Decays

10 Oct 2016 Chang Qin Li Xiao-Nan Sun Jun-Feng Yang Yue-Ling

In this paper, the contributions of weak annihilation and hard spectator scattering in $B\to \rho K^*$, $ K^* \bar{K}^*$, $\phi K^*$, $\rho\rho$ and $\phi\phi$ decays are investigated within the framework of QCD factorization. Using the experimental data available, we perform $\chi^2$ analyses of end-point parameters in four cases based on the topology-dependent and polarization-dependent parameterization schemes...
