The presented study of the radiative electroweak "penguin"--Decay B->K*(892)gamma, proceeding by the b->sgamma "loop"-transition, provides an important test of the Standard Model and a candidate of the search for New Physics. The used data sample has been recorded at the Y(4S) resonance with the BABAR detector at the asymmetric electron-positron- collider PEP-II of the Stanford Linear Accelerator Center (SLAC) in California. The B->K*gamma branching fractions are measured in four K*-decay modes. A search for direct CP-violation in the B->K*gamma mode has also been carried out.

The authors present measurements of branching fractions in the b 2!s{bar s}s penguin-dominated decays B 2![phi]K and B° 2![phi]K° in a sample of approximately 89 million B{bar B} pairs collected by the BABAR detector at the PEP-II asymmetric-energy B-meson Factory at SLAC. They determine [Beta](B+ 2![phi]K+) = (10.0{sub -0.8}{sup +0.9} ± 0.5) x 10−6 and [Beta](B° 2![phi]K°) = (8.4{sub -1.3}{sup +1.5} ± 0.5) x 10−6. Additionally, they measure the CP-violating charge asymmetry [Alpha]{sub CP}(B{sup ±} 2![phi]K{sup ±}) = 0.04 {+-} 0.09 {+-} 0.01, with a 90% confidence-level interval of [-0.10, 0.18], and set an upper limit on the CKM- and color-suppressed decay B+ 2![phi][pi]+, [Beta](B+ 2![phi][pi]+)

The authors present measurements of the CP-violation parameters S and C for the radiative decay B° →?K{sub S}°?; for B →?K? they also measure the branching fractions and for B →?K+? the time-integrated charge asymmetry?{sub ch}. The data, collected with the BABAR detector at the Stanford Linear Accelerator Center, represent 465 x 106 B{bar B} pairs produced in e+e− annihilation. The results are S = -0.18{sub -0.46}{sup +0.49} ± 0.12, C = -0.32{sub -0.39}{sup +0.40} ± 0.07,?(B° →?K°?) = (7.1{sub -2.0}{sup +2.1} ± 0.4) x 10−6,?(B+ →?K+?) = (7.7 ± 1.0 ± 0.4) x 10−6, and?{sub ch} = ( -9.0{sub -9.8}{sup +10.4} ± 1.4) x 10−2. The first error quoted is statistical and the second systematic.

The primary goals of the BABAR experiment are the detection of CP violation (CPV) in the B meson system, the precise measurement of some of the elements of the CKM matrix and the measurement of the rates of rare B meson decays. At present, BABAR has achieved major successes: (1) the discovery, in neutral B decays, of direct and mixing-induced CP violation; (2) accurate measurements of the magnitudes of the CKM matrix elements.
