Beschreibungen/Notizen

• We study D→ ππ decays with final state interactions considered in one-particle-exchange method. A clear physical picture for final state interactions based on quark and hadronic level diagrams is presented. A strong phase is introduced for hadronic effective couplings, which is crucial for explaining the experimental data of D +→ π + π 0, D 0→ π + π −, and D 0→ π 0 π 0. Rescattering effects between different D decay channels are usually large. They are important for obtaining correct branching ratios for D→ ππ decays in theoretical calculation.
