Description
We have applied the light-front formalism to calculate the electromagnetic form factors for the pion and the kaon from two models at low and high energies in order to explore the differences between such models. We have also compared the results for the ratio FK(Q2)/Fπ(Q2) with the experimental data up to 10 [GeV/c]2 and we have observed that the theoretical results are in good concordance for low energies, but they are very different at higher energy scales.
