摘要：
We analyze the B-0 -> a(0)(+/-)pi(-/+) and B--,B-0 -> f(0)K(-,0) decays and show that a consistent phenomenological picture can be obtained within the factorization approximation. In this approach the O-6, operator provides the dominant contributions to the suppressed channel B-0 -> a(0)(+)pi(-). An estimate of the annihilation form factor using perturbative QCD indicates that this contribution is not negligible, moreover interference with other penguin contributions includes a free parameter since the phase of the annihilation amplitude is not determined. Assumptions based on SU(2) isospin symmetry provide relations between different B decays involving one scalar and one pseudoscalar meson.
