摘要：

The interplay of strong and weak decay amplitudes for B -> pi pi K and B -> KKK, with the pi pi and KK pairs interacting in isospin-0 S-wave, is analyzed for pi pi effective mass from threshold to 1.2 GeV. To improve agreement with experiment of a factorization approach with some QCD corrections, addition of long-distance contributions, called charming penguins is necessary.
