Abstract：
Starting from the leading logarithmic low energy effective Hamiltonian and the Baner-Stech-Wirbel(BSW) model, we calculate the electroweak penguin effects in the two-body hadronic pure penguin processes of B-meson. In the case of B-PP and PV decays, we find that the processes involving external Penguin diagrams receive large contributim from electroweak penguin effects which can even play dominant role.
