Elastic charge form factors for K mesons

The elastic charge form factors for the charged K+ and neutral K0 are presented. The model employed makes use of solutions of the coupled Bethe-Salpeter and Schwinger-Dyson equations. This covariant model provides good predictions for the pionʹs elastic charge and transition form factor, and here we extend the model to include strange quarks. The results for the kaon are in good agreement with the available data. This model is partially motivated by the expectation of precision data from CEBAF approved experiment E-93-018. The non vanishing K0 form factor is due to the mass difference between the strange and down quarks.
