We comment on a recent suggestion for measuring $\gamma$ in $B^0(t)\to K_S\pi^+\pi^-$. A difficulty is pointed out in relating electroweak penguin and tree amplitudes in $B^+\to K^0\pi^+\pi^0$, which is crucial for an implementation of this method. We clarify the necessary condition for such a relation.

We express the amplitudes for charmless three-body B decays in terms of diagrams. As in two-body decays, we neglect annihilation-type contributions. When this is done, many of the exact, purely… Expand

Dalitz-plot analyses of $$B\rightarrow K\pi \pi $$B→Kππ decays provide direct access to decay amplitudes, and thereby weak and strong phases can be disentangled by resolving the interference patterns… Expand

We reexamine the question of measuring the weak phase $\ensuremath{\gamma}$ in $B\ensuremath{\rightarrow}K\ensuremath{\pi}\ensuremath{\pi}$ decays. To this end, we express all… Expand

We report results on the Dalitz analysis of three-body charmless B+ -> K+ pi(+) pi(-) and B+-> K+ K+ K- decays based on a 140 fb(-1) data sample collected with the Belle detector. Measurements of… Expand
