چکیده
We use recent data on K + → π + e + e − , together with known values for the pion form factor, to derive experimental values for the kaon electromagnetic form factor for 0 < q 2 < 0.125 (GeV/c) 2. The results are then compared with predictions of the Vector-Meson-Dominance model, which gives a good fit to the experimental results.

We use recent data on K + → π + e + e − , together with known values for the pion form factor, to derive the kaon electromagnetic form factor for 0 < q 2 < 0.125 (GeV/c) 2. The results are then compared with predictions of the Linear σ Model, a quark-triangle model and Vector Meson Dominance. The first two models describe the data at least qualitatively, but the simple Vector Meson Dominance pi...

The angle β is the most accurately measured quantity that determines the Unitarity Triangle. In this article I review the various measurements of this angle performed by the BaBar Collaboration, and discuss their implications in the search for new physics.

We extend our models for conformal sequestering of dynamical supersymmetry breaking with decoupling vector-like matter in several different ways. These extensions enable us to simplify concrete model building, in particular, rendering large gauge group and ad hoc global symmetry for sequestering unnecessary. Conformal sequestering appears highly natural in such circumstances.
