Summary
We present new measurements of time-dependent CP-violation parameters in hadronic penguin decays: B° → K⁺K⁻K{sub L}°, K{sub S}°π°π°, K{sub S}°K{sub S}°K{sub S}°, ωK{sub L}°, and a radiative penguin decay B° → K{sub S}°π°γ in a dataset of around 230 · 10⁶ B{bar B} pairs collected by the BABAR detector at the asymmetric B Factory at SLAC. These CP asymmetry measurements probe for amplitudes beyond the Standard Model in loop-dominated decays of neutral B mesons. While we find a puzzling deviation of CP-asymmetry parameters from predicted values, a full confirmation still awaits more data.
