We show that the nonlocality of the condensates is a key point to include nonperturbative contributions to the pion form factor. We compare our results with the Local-Duality predictions and show that the continuum threshold $s_0(Q^2)$ parameter is highly underestimated in the Local-Duality approach at $Q^2\\gtrsim 2$ GeV$^2$. Using our fit for this parameter, $s_0^\\text{LD}(Q^2)$, and applying the fractional analytic perturbation theory, we estimate with an accuracy of th","authors_text":"Alexander P. Bakulev, A. V.
