Analytic models of pion form factor
Description
An analytic Gounaris-Sakurai-like model with three parameters is considered. The pion form factor has an infinite-sheeted Riemann surface. The left cut of unphysical sheets is associated with the crossing-cut of p-wave of ππ scattering amplitude. A new parametrization of the model is proposed which is in better agreement with the experimental data. All parameters are physically clear
