- Summary
- We constrain the apex of the Cabibbo-Kobayashi-Maskawa unitarity triangle with measurements of B → K*π amplitudes from analyses of B° → K⁺π⁻π° and B° → K{sub S}π⁺π⁻ decays. This constraint is consistent with the world average. The B° → K⁺π⁻π° decay mode is reconstructed from a sample of 454 million B°{bar B}° events collected by the BABAR detector at SLAC. We measure direct CP violation in B° → K*⁺π⁻ decays at the level of 3σ when measurements from both B° → K⁺π⁻π° and B° → K{sub S}π⁺π⁻ decays are combined.
