Abstract

In this paper, the kaon electromagnetic form factor is calculated with a light-front constituent quark model (LFCQM). The electromagnetic components of the current (like the component "J+K") are extracted from the Feynman triangle diagram with the light-front approach. By means of the Feynmam diagram, we also obtained the electroweak decay constant and the charge radius for the kaon in the light-front approach. In this work, the kaon observables are calculated and a fairly good agreement is obtained with a very higher accuracy when compared with the experimental data.
