Abstract
We present a phenomenological analysis of the space- and time-like charged kaon electromagnetic form factors in factorized perturbative QCD (pQCD) by employing an analytic model for αs(Q2) and an infrared (IR) finite gluon propagator. In the space-like region, due to the lack of available experimental data above Q2 ∼ 0.2 GeV2, we only give our results for intermediate energies and make no comparison. In the time-like region, our results agree reasonably well with the available experimental data at moderate energies, including the CLEO data and the J/ψ result.
