The author presents measurements of radiative B meson decays to the final states Ks0[pi]0[gamma] and K[Phi][gamma] based on data collected at the [Upsilon](4S) resonance with the BABAR detector at the PEP-II e+e- collider at SLAC. In a data sample of 467 million B$\bar{B}$ pairs, the time-dependent CP asymmetry in B0 2!Ks0[pi]0[gamma] decays is measured in two regions of Ks0-[pi]0 invariant mass. In the K* region, 0.8

The author presents measurements of radiative B meson decays to the final states Ks0?0? and K?? based on data collected at the ?(4S) resonance with the BABAR detector at the PEP-II e+e- collider at SLAC. In a data sample of 467 million B$ar{B}$ pairs, the time-dependent CP asymmetry in B0 → Ks0?0? decays is measured in two regions of Ks0-?0 invariant mass. In the K* region, 0.8 m(Ksubs/subsup0/sup?sup0/sup) 1.0 GeV/csup2/sup, we find SsubK*?/sub = -0.03 ± 0.29 ± 0.03 and CsubK*?/sub = -0.14 ± 0.16 ± 0.03; in the range 1.1 m(Ksubs/subsup0/sup?sup0/sup) 1.8 GeV/csup2/sup, they find SsubKsubs/subsup0/sup/sub?sup0/sup? = -0.78 ± 0.59 ± 0.09 and C subKsubs/subsup0/sup/sub?sup0/sup? = -0.36 ± 0.33 ± 0.04. With a sample of 228 million B$ar{B}$ pairs they measure the branching fraction ?(Bsup+/sup → Ksup+/sup??) = (3.5 ± 0.6 ± 0.4) x 10sup-6/sup and set the limit ?(Bsup0/sup→ Ksup0/sup??) 2.7 x 10sup-6/sup at 90% confidence level. The direct CP asymmetry in Bsup+

This book contains the proceedings of the Fifth International Conference on Physics Beyond the Standard Models of Particle Physics, Cosmology and Astrophysics. It presents a brilliant overview of the status and future potential and trends in experimental and theoretical particle physics, cosmology and astrophysics, in the complimentary sectors of accelerator, non-accelerator and space physics.

Radiative and leptonic decays of B-mesons represent an excellent laboratory for the search for New Physics. I present here recent results on radiative and leptonic decays from the Belle and BABAR collaborations. Radiative penguin and leptonic B-meson decays are excellent probes for investigating the effects of New Physics. Although current measurements are in agreement with the Standard Model expectations, they are still quite useful for setting bounds on possible NP models. The B → X{sub s}[gamma] and B → [tau][nu] measurements, for example, put strong constraints on the mass of charged Higgs bosons in Type II two-Higgs double models. The B → X{sub s}[gamma] branching fraction measurements also constrain models with universal extra dimensions.

Rare B meson decays are an excellent probe for beyond the Standard Model physics. Two very sensitive processes are the B{sub s, d}° →??− and b → s?+?− decays. We report recent results at a center of mass energy of √s = 1.96 TeV from the CDF II and D0 collaborations using between 3.7 fb−1 and 6.9 fb−1 taken during Run II of the Fermilab Tevatron Collider.
