Electromagnetic Interactions of Kaons

Abstract

Analytical expressions for the electromagnetic form factors of the charged and neutral K mesons have been obtained in the Quark Confinement Model. The contribution from the direct diagrams, as well as that one from the intermediate vector states in the form fac­tors are examined.It is shown that for the description of the neutral K0 meson intermediate vector contribution is crucial. Electromagnetic radius of the charged kaon was calculated. fm. The received value (rK+) = 0.501 is in good agreement with the experimental data.The numerical values of the square of the electromagnetic radius of the neutral kaon at different values of the mixing angle of vector mesons was obtained.It was found that the best agreement with the experimental data is achieved when б = O.The calculated numerical value (rKo) = -0.084.
