Description
We present a calculation of the electromagnetic form factors (EFF) of the first and second radial excitation of pion.
We have employed a Schwinger-Dyson equations treatment of a vector × vector contact interaction which preserves key features of quantum chromodynamics, such as confinement, chiral symmetry breaking, axial-vector Ward-Takahashi identity and low-energy Goldberger-Treiman relations.
