Abstract: | We perform a model independent analysis of the pion electromagnetic formfactor using the available space like and time-like data. Our aim is to obtain information on the structure in the time-like region above the πω threshold. The phase below is assumed to be known from ππ scattering. In the process of analytic continuation we use as stabilizing lever different types of bounds on the derivative of the formfactor. |
