Using the general factorization approach, we present a detailed investigationfor the branching ratios, CP asymmetries and longitudinal polarizationfractions in all charmless hadronic $B \to VV$ decays (except for the pureannihilation processes) within the most general two-Higgs-doublet model withspontaneous CP violation. It is seen that such a new physics model only hasvery small contributions to the branching ratios and longitudinal polarizationfractions. However, as the model has rich CP-violating sources, it can lead tosignificant effects on the CP asymmetries, especially on those ofpenguin-dominated decay modes, which provides good signals for probing newphysics beyond the SM in the future B-physics experiments.
