In this paper, in order to probe the spectator-scattering and weak annihilation contributions in charmless Bs→ VV (where V stands for a light vector meson) decays, we perform the χ2-analyses for the endpoint parameters within the QCD factorization framework, under the constraints from the measured B¯ s→ ρ0ϕ, ϕK∗ 0, ϕϕ and K∗ 0K¯ ∗ 0 decays. The fitted results indicate that the endpoint parameters in the factorizable and nonfactorizable annihilation topologies are non-universal, which is also favored by the charmless B→ PP and PV (...
