Description
It was recently shown that the weak phase $\gamma$ can be extracted from three-body B decays. Using a flavor-SU(3)-symmetric approach, we extract $\gamma$ from the BaBar measurements of the Dalitz plots of $B \to K\pi\pi$ and $B \to KK\bar K$ decays. We find four possible solutions: $31^{+2}_{-3}$, $77\pm3$, $258^{+4}_{-3}$ and $315^{+3}_{-2}$, in degrees. In all cases the error includes first-order flavor-SU(3) breaking effects. One solution -- $77\pm3$ -- is consistent with the standard model; its error is smaller than that obtained using two-body B decays. We present recent updates of the results.
