P wave mesons emitting weak decays of bottom mesons

This paper is the extension of our previous work entitled Searching a systematics for nonfactorizable contributions to and hadronic decays. Obtaining the factorizable contributions from the spectator quark model for a systematics has been identified among the isospin reduced amplitudes for the nonfactorizable terms among decay modes. This systematics helps us to derive a generic formula which assists to predict the branching fractions for Inspired by this observation, we extend our analysis to p wave meson emitting decays of which have similar isospin structure and make predictions for where the experimental measurements are not yet available.

Searching a systematics for nonfactorizable contribution to B-and B0 mesons

Two-body weak decays / and are examined under isospin analysis to study nonfactorizable contributions. After extracting the strong phases and obtaining the factorizable contributions from spectator-quark diagrams for Nc=3, we determine nonfactorizable isospin amplitudes from the experimental data for these modes. Our results support the universality of ratio of nonfactorizable isospin reduced amplitudes for these decays within experimental errors. In order to show that this systematics is not coincidental, we also plot our results w. r. t. this ratio.

Quark Diagram Analysis of Bottom Meson Decays Emitting Pseudoscalar and Vector Mesons

This paper presents the two body weak nonleptonic decays of B mesons emitting pseudoscalar (P) and vector (V) mesons within the framework of the diagrammatic approach at flavor SU(3) symmetry level. Using the decay amplitudes, we are able to relate the branching fractions of B PV decays induced by both b c and b u transitions, which are found to be well consistent with the measured data. We also make predictions for some decays, which can be tested in future experiments.
