Factorization And New Physics In B→VV

In the heavy quark mass limit, we get the spin and flavor symmetry between heavy quarks. This makes it is possible to develop an effective theory at low energy scale to describe B physics easily. Factorization are used to calculate the process with two final states go away fast. So the decay amplitude can be divided into two parts, because there is no exchange of hard gluons. We can detect the polarization in B→VV, which pro-vide abundance information in B physics. Also we can use these processes researching CP violation and CKM elements, we may find big CP asymmetry in B→ρK*. Fac-torization works well in color-allowed processes, but gets troubles in color-suppressed processes. Some high order corrections related to hadronic part are hard to calculate. Since they are small enough compared to the color-allowed tree contribution, we ignore them. But in the color-suppressed tree dominant or penguin dominant decays, these contributions can not be ignored as high order correction. QCDF, PQCD, SCET and FSI are all developed in the foundation of naive factorization. But these theory have their own problems. We consider these additional effects phenomena, eliminate those contradict to experiment results in some aspects. The most possible explanations are rescattering and annihilation, they can improve the transverse polarization of the pen-guin dominant processes, such as B→φK*, without changing their branch ratio lots. But the FSI have lots of internal states and annihilation contribution can not calculated by perturbative method. Fortunately, these non-factorization effects act on decay matrix in a similar way, they can be described by a same anomaly operator. With SU(3) sym-metry, there are just two hadronic parameters left. We can fit them by datum from pure penguin processes. The method is perspective. Compared with NF, our work explain the puzzles of transverse anomalous in penguin dominant decays and the branch ratio, CP asymmetry anomaly in B→ρρand B→ππ. We also improve the branch ratio of B→ρ0ρ0, although PQCD can explain it in another way.Another work we do is researching the form factors of B→K*. In the decays with large momentum transfer, form factors can change as pole term or exponential term of momentum, as described by Ali and Ball. We choose the simple pole term, restrict the form factors by symmetry relations in heavy quark mass limits. Then we can fit them by datum from experiment and get the transform in whole phase space. We check the form factors near the zero quantum in semileptonic decays of B→K*.Adding SUSY models our works can give different figures in new physics from Alis' assumption.
