Resumo:The pion mass dependence of the pion vector form factor is investigated using the Omnes representation. Our prediction agrees with later lattice results quite well. The nice agreement of the pion mass dependence of the scattering lengths of the charmed mesons and light pseudoscalar mesons suggests that the D(s0)(2317)* be a DK bound state. Furthermore, it is argued that the kaon mass dependence of a kaonic bound state should be linear, and can be used as a criterion in determining the nature of such a bound state on lattice.
