Description

Electromagnetic form factor of the Pion is calculated in the framework of chiral effective field theory with vector mesons included as dynamical degrees of freedom. Results are given for the time-like region up to q2∝1 GeV2. To construct an effective field theory with a consistent power counting the complex-mass-renormalization scheme is applied. This can be interpreted as the on-mass-shell renormalization scheme for unstable particles. Reasonably good description of the data is obtained already at next-to-leading order within the given approach.
