Abstract
The modified flat-bottom potential (MFBP) is given by the combination ofthe flat-bottom potential with considerations for the infrared andultraviolet asymptotic behaviour of the effective quark-gluon coupling.The π meson electromagnetic form factor is calculated in theframework of the coupled Schwinger-Dyson equation and the Bethe-Salpeterequation in the simplified impulse approximation (dressed vertex)with the MFBP. All our numerical results give a good fit toexperimental values.
