Extraction of the CP-violating phase γ using B→Kππ and B→KKK¯ decays

Using the BaBar measurements of the Dalitz plots for B0→K+π0π−, B0→K0π+π−, B+→K+π+π−, B0→K+K0K−, and B0→K0K0K¯0 decays, we demonstrate that it is possible to cleanly extract the weak phase γ. We find four possible solutions. Three of these - 32°, 259°, and 315° - are in disagreement with the SM, while one - 77° - is consistent with the SM. An advantage of this Dalitz-plot method is that one can obtain many independent measurements of γ, thereby reducing its statistical error. An accurate determination of the errors, however, requires detailed knowledge of the data.
