Test of FSR in the process $e^+e^-\to\pi^+\pi^-\gamma$ at DA$\Phi$NE and extraction of the pion form factor at threshold

Effects due to non-pointlike behaviour of pions in the process $e^{+} e^{-} \to π^{+} π^{-} γ$ can arise for hard photons in the final state. By means of a Monte Carlo event generator, which also includes the contribution of the direct decay $ϕ \to π^{+} π^{-} γ$ , we estimate these effects in the framework of Resonance Perturbation Theory. We consider angular cuts used in the KLOE analysis of the pion form factor at threshold. A method to reveal the effects of non-pointlike behaviour of pions in a model-independent way is proposed.
