We study the narrow decay width of low-lying penta-quark baryons in the QCD string theory in terms of gluonic excitations. In the QCD string theory, the penta-quark baryon decays via a gluonic-excited state of a baryon and meson system, where a pair of Y-shaped junction and anti-junction is created. Since lattice QCD shows that the lowest gluonicexcitation energy takes a large value of about 1 ...

We use a spectator framework to investigate the spectral properties of quark-quarkgluon correlators and use this to study gluonic pole matrix elements. Such matrix elements appear in principle both for distribution functions such as the Sivers function and fragmentation functions such as the Collins function. We find that the contribution of the gluonic pole matrix element in fragmentation func...

We investigate the spectral properties of quark-quark-gluon correlators and use this to study gluonic pole matrix elements. Such matrix elements appear in principle both for distribution functions such as the Sivers function and fragmentation functions such as the Collins function. We find that for a large class of spectator models, the contribution of the gluonic pole matrix element for fragme...

Penguins are an important seabird species in Antarctica and are sensitive to climate and environmental changes. Previous studies indicated that penguin populations increased when the climate became warmer and decreased when it became colder in the maritime Antarctic. Here we determined organic markers in a sediment profile collected at Cape Bird, Ross Island, high Antarctic, and reconstructed t...

We calculate penguin contributions to the lifetime splitting between the Bs and the Bd meson. In the Standard Model the penguin effects are found to be opposite in sign, but of similar magnitude as the contributions of the current-current operators, despite of the smallness of the penguin coefficients. We predict τ(Bs) τ(Bd) − 1 = (−1.2± 10.0) · 10 · ( fBs 190MeV )2 , where the error stems from...

We discuss a possibility of large electroweak (EW) penguin contribution in B → Kπ and ππ. The recent experimental data may be still suggesting that there are some discrepancies between the data and theoretical estimations. In B → Kπ decays, to explain several theoretical relations among the branching ratios, a slightly large electroweak penguin contribution and large strong phase differences or...

The fledging mass of penguin chicks can be an indicator of food availability and environmental conditions at a penguin colony. For the period 1989 to 2011, we analyzed predictor variables of environmental and food resource factors acting on multiple spatial scales near Palmer Station, Antarctica, that may influence the interannual variability in Adélie penguin chick fledging mass (CFM). To unde...

Penguin contributions, being not negligible in general, can hide the information on the CKM angle α coming from the measurement of the timedependent B0(t) → π+π− CP-asymmetry. Nevertheless, we show that this information can be summarized in a set of simple equations, expressing α as a multi-valued function of a single theoretically unknown parameter, which conveniently can be chosen as a well-d...

on a Relational Database1 Tetsuya Takahashi Arthur M. Keller Kobe Steel, Ltd. Stanford University Abstract We present the implementation of the query function for the Penguin system. Penguin is an object-oriented database system that supports multiple object views on a relational database. It enables many applications to share a database using di erent object schemata. Also, users can take quer...

Recent research has shown that infants as young as 13 months can attribute false beliefs to agents, suggesting that the psychological-reasoning subsystem necessary for attributing reality-incongruent informational states (Subsystem-2, SS2) is operational in infancy. The present research asked whether 18-month-olds' false-belief reasoning extends to false beliefs about object identity. Infants w...
