Calculation of kaon electromagnetic form factor

The kaon meson electromagnetic form factor is calculated in the framework o f coupled Schwinger-Dyson and Bethe-Salpeter formulation in simplified impu lse approximation (dressed vertex) with modified flat-bottom potential, whi ch is a combination of the flat-bottom potential taking into consideration the infrared and ultraviolet asymptotic behaviours of the effective quark-g luon coupling. All the numerical results give a good fit to experimental va lues.
