Scientific paper

Charged and neutral B decays into the pi+pi-K, K+K-K and K0S K0S K0S systems have been studied. The pi+pi- and K+K- final state interactions in the S-wave isoscalar state are treated in an unitary way. The long-distance contributions called charming penguins are introduced in the model. Effective mass distributions, branching ratios and some asymmetries are succesfully compared with the recent BaBar and Belle data. A particularly large negative direct CP-violating asymmetry in the charged B decays into f0(980)K is evaluated for one set of the charming penguin amplitudes.
