Abstract: | The issue of Kπ and ππ S-wave amplitude is addressed using decays of D-mesons. Model-independent measurements of the phases of the π + π + and K - π + S-wave amplitude from D +→π - π + π + and D +→K - π + π + decays are discussed. The result indicates a deviation from the phase of the K - π + S-wave amplitude obtained by scattering experiments. This could be interpreted as an indication of the presence of 3-body final-state interaction, or in other words, that the phases from production and scattering process cannot be directly compared. |
