## Abstract

We show how theoretical, principally lattice calculations of the scalar form factors in semileptonic pseudoscalar-to-pseudoscalar decays can be used to extract information about the corresponding elastic s-wave scattering channels. We find values for the scattering lengths mpia=0.179(17)(14), 0.26(26) and 0.29(4) for elastic s-wave isospin-1/2 Kpi, Bpi and Dpi channels, respectively. We also determine phase shifts. For the DK channel we find hints that there is a bound state which can be identified with the recently discovered Ds0+(2317).
