SU(3) Analysis of Annihilation Contributions and CP Violating Relations in B → PP Decays
نویسنده
چکیده
Several methods proposed to measure the angle γ in the KM unitarity triangle assumed that the tree contribution to B− → π−K̄0 is purely due to annihilation contributions and is negligibly small. This assumption has to be tested in order to have a correct interpretation of the experimental data. In this paper we show that using SU(3) symmetry, the smallness of the tree contribution can be tested in a dynamic model independent way. We also derive several relations between CP violating rate differences for B → PP decays without assuming the smallness of the annihilation contributions. These relations provide important tests for the Standard Model of CP violation. PACS numbers: 13.20.He, 11.30.Er, 12.38.Bx Typeset using REVTEX

With SU(3) symmetry one only needs 13 hadronic parameters to describe B → P P decays in the Standard Model. When annihilation contributions are neglected, only 7 hadronic parameters are needed. These parameters can be determined from existing experimental data and some unmeasured branching ratios and CP asymmetries of the type B → P P can be predicted. In this talk we present SU(3) predictions ...

In this paper, we study nonleptonic charmless B decays to two light pseudoscalar mesons within the frame of QCD factorization, including the contributions from the chirally enhanced power corrections and weak annihilation. Predictions for the CP-averaged branching ratios and CP-violating asymmetries are given. Within the reasonable range of the parameters, we find that our predictions for the b...
متن کاملRelations for Direct CP asymmetries in B → PP and B → PV decays 1
ABSTRACT The presence of additional strong phase from power corrections and other chirally enhanced terms makes it more difficult to predict direct CP asymmetries in two-body charmless B decays. In this talk, I would like to report on a recent work on QCD Factorisation and Power Corrections in Charmless B Decays. Using the measured branching ratios for B → PV, it is shown that power corrections...
متن کاملDecays of B mesons to two light pseudoscalars.
The decays B → PP , where P denotes a pseudoscalar meson, are analyzed, with emphasis on charmless final states. Numerous triangle relations for amplitudes hold within SU(3) symmetry, relating (for example) the decays B → ππ, πK, and πK. Such relations can improve the possibilities for early detection of CP -violating asymmetries. Within the context of a graphical analysis of decays, relations ...
متن کاملNonleptonic Cabibbo favoured B - decays and CP - asymmetries for Charmed final hadron states in Isgur and Wise theory 1
The Cabibbo allowed non-leptonic B-decays in two hadrons are studied, within the factorization hypothesis , in the framework of Isgur and Wise theory for the matrix elements of the ∆B = −∆C = ±1 weak currents. The SU (2) HF symmetry relates |∆B| = 1 to |∆C| = 1 currents, which have been measured in the semileptonic strange decays of charmed particles. By assuming colour screening and allowing f...
