Can One Measure the Weak Phase of a Penguin Diagram?
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...
متن کاملSpacelike Branes
Scalar field theories with appropriate potentials in Minkowski space can have timedependent classical solutions containing topological defects which correspond to S-branes i.e. branes all of whose tangential dimensions are spacelike. It is argued that such Sbranes arise in string theory as time-dependent solutions of the worldvolume tachyon field of an unstable D-brane or D-brane-anti-D-brane p...
متن کاملPenguin Topologies , Rescattering Effects and Penguin Hunting with B u , d → KK and B ± → π ±
In the recent literature, bounds on the CKM angle γ arising from combined branching ratios for Bd → πK and B → πK decays received a lot of attention. If the ratio R of these branching ratios is found experimentally to be smaller than 1 – present CLEO results give R = 0.65± 0.40 – these bounds can be considered as almost model independent. It has recently been argued that rescattering effects, s...
متن کاملSpacelike intersection curve of three spacelike hypersurfaces in E 41
In this paper, we compute the Frenet vectors and the curvatures of the spacelike intersection curve of three spacelike hypersurfaces given by their parametric equations in four-dimensional Minkowski space E 1 .

In the recent literature, bounds on the CKM angle γ arising from combined branching ratios for Bd → πK and B → πK decays received a lot of attention. If the ratio R of these branching ratios is found experimentally to be smaller than 1 – present CLEO results give R = 0.65 ± 0.40 – these bounds are free of hadronic uncertainties at the level of 1%. It has recently been argued that rescattering e...
