Book Description
"The upper limit for the B0d→K*0g decay is consistent with the branching fraction measurement reported by the CLEO collaboration, B&parl0;B0d→K*0 g&parr0; = (4.0 +/- 1.9) x 10-5, while the upper limit for the as yet unobserved B0s→fg decay is the most constraining one set to date." --

Book Description
Electromagnetic radiative penguin decays of the B meson were studied with the BaBar detector at SLAC's PEP-II asymmetric-energy B Factory. Branching fractions and isospin asymmetry of the decay B → K*[gamma], branching fractions of B → K*2(1430)[gamma], and a search for B° → [phi][gamma] are presented. The decay rates may be enhanced by contributions from non-standard model processes.

Book Description
We report on the search for B°{sub s}→??−, B°{sub d}→?+?− decays and b→ s?+?− transitions in exclusive decays of B mesons using the CDF II detector at the Fermilab Tevatron Collider. Using 2 fb−1 of Run II data we find upper limits on the branching fractions?(B°{sub s}→?+?−)

Book Description
Radiative and electroweak penguin decays of B mesons are flavor-changing-neutral-current processes that provide powerful ways to test the Standard Model at the one-loop level, to search for the effects of new physics, and to extract Standard Model parameters such as CKM matrix elements and quark masses. The large data samples obtained by the B-factory experiments BaBar and Belle, together with an intensive theoretical effort, have led to significant progress towards understanding these rare decays. Recent experimental results include the measurements of the b 2!d[gamma] decays B 2[gamma], the observation of B 2!K(*)ll− decays (together with studies of the associated kinematic distributions), and improved measurements of the inclusive B 2!Xs[gamma] rate and photon energy spectrum.

Book Description
The high cross-section for the production of b quarks at the Tevatron hadron collider make it an ideal place to search for rare B meson species and very low branching fraction decay modes of the more common B mesons. This paper reports the recent discovery of the Bc meson by the CDF collaboration. It also discusses the observation of rare B meson final states involving [psi](2S) mesons and searches for ultra-rare decays such as B [yields] [mu][sup +][mu][sup -].
