Abstract
The charged and neutral kaon form factors are calculated as a phenomenological application of model QCD Dyson-Schwinger equations. The results are compared with the pion form factor calculated in the same framework and yield FK± (Q2) > Fπ± (Q2) on Q2 ∈ [0, 3] GeV2; and a negative charge radius for the neutral kaon. These results are sensitive to the difference between the kaon and pion Bethe-Salpeter amplitude and the u-and s-quark propagation characteristics.
