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: $(31^{+2}_{-3})^\circ$, $(77 \pm 3)^\circ$, $(258^{+4}_{-3})^\circ$, and $(315^{+3}_{-2})^\circ$. 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…

O ct 2 01 3 Measurement of γ from three-body B decays

Using the BABAR measurements of the Dalitz plots for the decays B0 → K+π0π−, B0 → K0π+π−, B+ → K+π+π−, B0 → K+K0K−, andB0 → K0K0K̄0, we demonstrate that it is possible to cleanly extract the weak



Study of CP violation in Dalitz-plot analyses of B0 --> K+K-K0(S), B+ --> K+K-K+, and B+ --> K0(S)K0(S)K+

We perform amplitude analyses of the decays B^0→K^+K^-K_S^0, B^+→K^+K^-K^+, and B^+→K_S^0K_S^0K^+, and measure CP-violating parameters and partial branching fractions. The results are based on a data

Evidence for Direct CP Violation from Dalitz-plot analysis of $B^\pm \to K^\pm \pi^\mp \pi^\pm$

We report a Dalitz-plot analysis of the charmless hadronic decays of charged B mesons to the final state K-+/-pi(-/+)pi(+/-). Using a sample of (383.2 +/- 4.2) x 10(6) B (B) over bar pairs collected

Amplitude analysis of B0→K+π-π0 and evidence of direct CP violation in B→K*π decays

We analyze the decay B0-->K+ pi- pi0 with a sample of 454 million B Bbar events collected by the BaBar detector at the PEP-II asymmetric-energy B factory at SLAC, and extract the complex amplitudes

Time-dependent amplitude analysis of B0 -> KS0π+π-

We perform a time-dependent amplitude analysis of B-0 -> K-S(0)pi(+)pi(-) decays to extract the CP violation parameters of f(0)(980)K-S(0) and rho(0)(770)K-S(0) and the direct CP asymmetry of

Amplitude analysis and measurement of the time-dependent CP asymmetry of B0→KS0KS0KS0 decays

We present the first results on the Dalitz-plot structure and improved measurements of the time-dependent CP-violation parameters of the process B^0→K_S^0K_S^0K_S^0 obtained using 468×10^6  BB decays

Model independent electroweak penguins in B decays to two pseudoscalars

We study the effects of electroweak penguin (EWP) amplitudes in B meson decays into two charmless pseudoscalars in the approximation of retaining only the dominant EWP operators Q9 and Q10. Using
