We present the query processing algorithm for the Penguin system. Penguin supports multiple object views on a relational database, so that data may be shared by applications with heterogeneous object schemata. Penguin also o ers an interface for the C++ language. We have developed a query processing algorithm for querying composite object views. The query algorithm takes a query on a composite ...

gies for determining the Unitarity Triangle in these modes. Computing the penguin parameters (r±,φ±) and the ratio of two trees (rt ,φt ) within QCD factorization yields a precise determination of (ρ̄ , η̄), reflected by a weak dependence on φ±, which is shown to be a second order effect, as in the Bd → π+π− system. Moreover, we find that the dependence on penguin amplitudes r± in Bd → ρ±π∓ is le...

We report on preliminary results of searches for penguin mediated B decays based on 20.7 fb −1 of data collected at the Υ (4S) peak with the BABAR detector at PEP-II. The following branching fractions have been measured: B(B + → φK +) = (7.7 −5.6 ± 1.7) × 10 −6 , where the first error is statistical and the second systematic. For several other modes we report upper limits on their branching fra...

The b → d penguin amplitude receives contributions from internal u, c and t-quarks. We show that it is impossible to measure the weak phase of any of these penguin contributions without theoretical input. However, it is possible to obtain the weak phase if one makes a single assumption involving the hadronic parameters. With such an assumption, one can test for the presence of new physics in th...

We review the effective Lagrangian of the Higgs penguin in the Standard Model and its minimal supersymmetric extension (MSSM). As a master application of the Higgs penguin, we discuss in some detail the B-meson decays into a lepton-antilepton pair. Furthermore, we explain how this can probe the Higgs sector of the MSSM provided that some of these decays are seen at Tevatron Run II and B-factori...

We analyse photonic penguin contributions to the rare decay B → K * γ by taking into account the correction of order m K * /m B and the bound state effect in the perturbative QCD framework. It is shown that the contributions coming from both of photonic penguin diagrams should be calculated since the contribution from the second photonic penguin diagram is enhanced by the bound state effect. Th...

Recently, a new hadronic structure at around $6.9$ GeV was observed in an LHCb experiment. From its limited yet known decay mode, one could still determine that it contains least four charm quarks and hence belongs to the category of exotic state. This finding indicates for first time tetracharm states is therefore quite importance. In this letter, we propose nature hybrid interpretation $X(690...
