B and $B_{s}$ decays into three pseudoscalar mesons and the determination of the angle $\gamma$ of the unitarity triangle
We reconsider two classical proposals for the determination of the angle gamma of the unitarity triangle: B^\pm => chi_{c0} \pi^\pm => \pi^+\pi^-\pi^\pm and B_s => rho^0 K_S => \pi^+ \pi^- K_S. We point out the relevance, in both cases, of non resonant amplitudes, where the \pi^+ \pi^- p...
