摘要：
To describe the weak three-body decays B -> pi(+)pi K-, we recently derived amplitudes based on two-body QCD factorization followed by pi(+)pi(-) final state interactions in isoscalar S- and isovector P-waves. We study here the sensitivity of the results to the values of the B to f(0)(980) transition form factor and to the effective decay constant of the f(0)(980).
