Query: Long-distance effects and final state interactions in B to pion pion K
  and B to K anti-K K decays   B decays into pion pion K and K anti-K K, where the pion-pion and anti-K K
pairs interact in isospin zero S-wave, are studied in the pion-pion effective
mass range from threshold to 1.2 GeV. The interplay of strong and weak decay
amplitudes is analyzed using an unitary pion-pion and K anti-K coupled channel
model. Final state interactions are described in terms of four scalar form
factors constrained by unitarity and chiral perturbation theory. Branching
ratios for the B decay into f0(980)K, calculated in the factorization
approximation with some QCD corrections, are too low as compared to recent
data. In order to improve agreement with experiment, we introduce long-distance
contributions called charming penguins. Effective mass distributions, branching
ratios and asymmetries are compared with the existing data from BaBar and Belle
collaborations. A particularly large negative asymmetry in charged B decays is
predicted for one set of the charming penguin amplitudes.
