Abstract
We calculated the elastic form factor of pion-like mesons with masses \(m_{0^-}/GeV = 0.14, 0.47, 0.69, 0.83\) on the space-like domain, upto \(Q^2/GeV ^2 = 4, 5, 6, 7\) respectively. Comparing the preliminary lattice QCD results with ours, we find that the form factors on the domain \(Q^2 < 1.0 GeV ^2\) are consistent, while the lattice QCD results can not all fit our pattern of the mass denpedence of the form factor on larger \(Q^2\) region.
