We study the rates and direct $CP$ violations of two-body baryonic ${\overline{B}}_{u,d,s}\ensuremath{\rightarrow}{\mathbf{\text{B}}\overline{\mathbf{\text{B}}}}^{\ensuremath{'}}$ ${B}_{c}^{\ensuremath{-}}\ensuremath{\rightarrow}{\mathbf{\text{B}}\overline{\mathbf{\text{B}}}}^{\ensuremath{'}}$ decays, where final state baryons include low-lying octet decuplet baryons. incorporate topological am...

The measurements of B → πK decays have been in disagreement with the predictions of the Standard Model (SM) for some time. In this paper, we perform an update of this puzzle using the latest (2008) data. We find that the situation has become far less clear. A fit to the B → πK data alone suggests the presence of new physics (NP). Indeed, if one adds a constraint on the weak phase γ coming from ...

At present, there are discrepancies between the measurements of several observables in B → πK decays and the predictions of the standard model (the “B → πK puzzle”). Although the effect is not yet statistically significant – it is at the level of >∼ 3σ – it does hint at the presence of new physics. In this paper, we explore whether supersymmetry (SUSY) can explain the B → πK puzzle. In particul...

We calculate the decay constants of Ds and D∗ s with B̄0 → D+`−ν and B̄0 → D+D−(∗) s decays. In our analysis we take the factorization method with considering non-factorizable term contributions and used two different form factor behaviours (constant and monopoletype) for F0(q). We also consider the QCD-penguin and Electroweak-penguin contributions in hadronic decays within the NDR renormalizatio...

We report recent results in the study of rare hadronic and radiative penguin decays of B mesons. These results are based on a sample of 23 million BB pairs collected by the BABAR Collaboration at the SLAC PEP-II ee B Factory. Contributed to the Proceedings of the 5 KEK Topical Conference: Frontiers In Flavor Physics (KEKTC5), 20-22 Nov 2001, Tsukuba, Ibaraki, Japan. Stanford Linear Accelerator ...

“Penguin Hockey”: A Tangible Playroom for Children Akihiko Shirai, Shouichi Hasegawa, Yasuharu Koike and Makoto Sato Precision and Intelligence Laboratory, Tokyo Institute of Technology. We have developed an interactive installation called "Penguin Hockey". It is a demonstration content of "Tangible Playroom" for children. Tangible playroom looks an empty children's room but it has large tangib...

The diffusion of standards is characterized by network effects, path dependency, and the penguin effect. Particularly the latter, also referred to as excess inertia, is a frequent inhibitor of the adoption of standards, even if they could provide benefits. This is particularly true for item master data pools that suffer from little adoption in many industries as benefits can only accrue if many...

Penguin is designed to support object-orientation for application programs while using relational databases as the persistent backing store. Objects are attractive to customers and programmers of applications because they structure information into a relevant and effective view. The use of relational databases that store of large amounts of base data for long periods of time enables Penguin to ...

We complete the computation of the 1-loop (αs) corrections to hard spectator scattering in non-leptonic B decays at leading power in Λ/mb by evaluating the penguin amplitudes. This extends the knowledge of these next-to-next-to-leadingorder contributions in the QCD factorization formula for B decays to a much wider class of final states, including all pseudoscalar-pseudoscalar, pseudoscalar-vec...
