Final state interactions in $B \to \pi\piK and B \to K\bar{K}K$ decays

Abstract : Analysis of charged and neutral B meson decays into pi+ pi- K, K+ K- K and K0S K0S K0S is performed using a unitary representation of the pi pi and K anti- K final state interactions. Comparison of the theoretical model with the experimental data of the Belle and BaBar Collaborations indicates that charming penguin contributions are necessary to describe the B --> f0(980) K and B --> rho(770) K decays.
