Abstract: | Using the light-front K⁺-Meson wave function based on a Bethe-Salpeter amplitude model for the Quark-Antiquark bound state, we study the Electromagnetic Form Factor (EMFF) of the K⁺-Meson in nuclear medium within the framework of light-front field theory. The K⁺-Meson model we adopt is well constrained by previous and recent studies to explain its properties in vacuum. The in-medium K⁺-Meson EMFF is evaluated for the plus-component of the electromagnetic current, J⁺, in the Breit frame. In order to consistently incorporate the constituent up and antistrange Quarks of the K⁺-Meson immersed in symmetric nuclear matter, we use the Quark-Meson coupling model, which has been widely applied to various hadronic and nuclear phenomena in a nuclear medium with success. We predict the in-medium modification of the K⁺-Meson EMFF in symmetric nuclear matter. It is found that, after a fine tuning of the regulator mass, i.e. mR = 0.600GeV, the model is suitable to fit the available experimental data in vacuum within the theoretical uncertainties, and based on this we predict the in-medium modification of the K⁺-Meson EMFF. |
