abstractNote = {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 m{sub {pi}}a=0.179(17)(14), 0.26(26) and 0.29(4) for elastic s-wave isospin-1/2 K{pi}, B{pi} and D{pi} 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 D{sub s0}{sup +}(2317)},
