Description
We present a calculation of the electromagnetic form factors (EFF) of the radially excited and ground state for pion and kaon.
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. We compare our results for the electromagnetic form factors the charge radii with those obtained through Schwinger-Dyson equations involving more sophisticated interaction kernels and experimental data whenever is possible.
