2 INTRODUCTION In the Standard Model (SM, Charmless hadronic B decays occur mainly via two processes. (i b s penguin diagram (ii b u tree diagram Charmless hadronic B-decays give us plenty of information. * Search for new physics effects by studying loop processes. * b s quark transitions are sensitive to physics beyond SM. * Direct CP Violation : Interefering SM amplitudes. * Measuring BF, angular correlations could help the phenomenological test/development of the theoretical models. Sunghyon Kyeong (Yonsei Univ. b s Hadronic Decay at Belle July 16-, 9 /
3 MOTIVATION * Measurements of f L in rare B decays to VV, such as B φk, have revealed an unexpectedly large fraction of transverse polarisation. * This implies that non-factorizable contributions to the decay amplitude play a significant role. * Further information about these effects can be obtained with B and f L in B ρ K (also b s penguin-dominated.
