# The Kpi and pipi S-wave from D decays - High Energy Physics - Experiment

Abstract: This paper is focused on two issues: the K\pi spectrum near threshold - thekappa problem -, and the pi\pi spectrum between 1.2 and 1.5 GeV-c^2 - thef 01370 problem. Both problems will be analysed from the perspective of the$D$ meson decays, with some additional information from $\tau$ and B decays.
