A Kerr metric describing a rotating black hole is obtained on the three brane in a fivedimensional RandallSundrum brane world by considering a rotating fivedimensional black string in the bulk. We examine the causal structure of this spacetime through the geodesic equations.

Results of the quasielastic neutron scattering (QENS) measurements on the dynamics of excess water in hydrotalcite sample with varied content of excess water are reported. Translational motion of excess water can be best described by random translational jump diffusion model. The observed increase in translational diffusivity with increase in the amount of excess water is attributed to the change in binding of the water molecules to the host layer.

The dynamics of a flat isotropic brane Universe with twocomponent matter source —perfect fluid with the equation of statep = (γ − 1)ρ and a scalar field with a powerlaw potentialV ∼ φ^{α} is investigated. We describe solutions for which the scalar field energy density scales as a powerlaw of the scale factor. We also describe solutions existing in regions of the parameter space where these scaling solutions are unstable or do not exist.

Measuring the angle γ of the unitarity triangle is an important part of overconstraining the standard model’s explanation of CP violation and testing for new physics contributions to CP violation. Although there are many ways to measure γ, all of them have significant experimental or theoretical challenges. This talk presents progress at the BABAR experiment toward measuring γ usingB meson decays.
