Measurements Of Time Dependent Cp Violation In Radiative B Decays At Babar

The authors present measurements of the CP-violation parameters S and C for the radiative decays B° →?°K{sub S}°? and B° →?K{sub S}°?; for B →?K? they also measure the branching fractions and for B →?K+? the time-integrated charge asymmetry A{sub ch}. The data, collected with the BABAR detector at the SLAC National Accelerator Laboratory, represent 467 x 106 B{bar B} pairs produced in e+e− annihilation at the PEP-II collider. In this summary they present an updated measurement of the time-dependent CP asymmetry in B° →?°K{sub S}°? decay mode and the first measurement of the time-dependent CP asymmetry in B° →?K{sub S}°? decay mode. Hadronic corrections in B° →?°K{sub S}°? decay mode might permit S to be as large as ± 0.1. Such corrections and NP effects could depend on m(?°K{sub S}°), so they split the data into two parts: the K*(892) region with 0.8
