Measurement of gamma using B -> K pi pi and B -> K K Kbar decays

Abstract

The BaBar measurements of the Dalitz plots for B0 -> K+ pi0 pi-, B0 -> K0 pi+ pi-, B+ -> K+ pi+ pi-, B0 -> K+ K0 K-, and B0 -> K0 K0 Kbar0 decays are used to cleanly extract the weak phase gamma. We find four possible solutions: $(31_{-3}^{+2}{)}^{\circ }$, $(77\pm 3{)}^{\circ }$, $(258_{-3}^{+4}{)}^{\circ }$, and $(315_{-2}^{+3}{)}^{\circ }$. One solution -- $(77\pm 3{)}^{\circ }$ -- is consistent with the SM. Its error, which includes leading-order flavor-SU(3) breaking, is far smaller than that obtained using two-body B decays.
