Factorizable amplitudes in B decays to light vector meson pairs give a longitudinal polarization satisfying 1 - f(L) = O(1/m(b)(2)). This remains formally true when non-factorizable graphs are included in QCD factorization, and is numerically realized in B --> rhorho. In DeltaS = 1 decays a QCD penguin annihilation graph can effectively contribute at leading power to the transverse and longitudinal amplitudes. The observed longitudinal polarization, f(L)(B --> phiK*) approximate to 50, can therefore be accounted for in the SM. The ratio of transverse rates Gamma(perpendicular to)/Gamma(parallel to) provides a sensitive test for new right-handed currents. The transverse b --> sg dipole operator amplitudes are highly suppressed. CP violation measurements can therefore discriminate between new contributions to the dipole and four quark operators. SU(3)(F) violation in QCD penguin amplitudes can easily be O(1), in general, due to annihilation. Implications for B --> rhoK* polarization and New Physics searches are pointed out.

机译：B衰减到光矢量介子对的可分解振幅给出满足1 - f（L） = O（1/m（b）（2））的纵向偏振。当不可分解图包含在 QCD 因式分解中时，这在形式上仍然是正确的，并且在 B --> rhorho 中以数值方式实现。在 DeltaS = 1 衰减中，QCD 企鹅湮灭图可以有效地为横向和纵向振幅提供领先功率。因此，观测到的纵向极化f（L）（B --> phiK*）约为50%，因此可以在SM中解释。横向速率 Gamma（垂直于）/Gamma（平行于）的比率为新的右手电流提供了灵敏的测试。横向 b --> sg 偶极子算子振幅受到高度抑制。因此，CP违规测量可以区分对偶极子和四夸克算子的新贡献。QCD企鹅振幅中的SU（3）（F）违规通常很容易成为O（1），这是由于湮灭。指出了对 B -->rhoK* 极化和新物理研究的影响。（C） 2004年，Elsevier B.V.保留所有权利。
