(Color online) Fit results for the pion form factor in the e+e−→π+π− process (a) and τ→ντ2π process (b). The data of e+e− annihilation are taken from the OLYA and CMD,[41] CMD2,[42–43] DM1,[44] SND,[45] KLOE,[1–2] BESIII[3] collaborations. The τ decay data are taken from the ALEPH[46] and CLEO[25] collaborations. The solid lines are our theoretical predictions.
