Exclusive Production Ratio of Neutral over Charged Kaon Pair in $e^{+}{e}^{-}$ Annihilation Continuum via `Straton Model'

Abstract

A completely relativistic quark model in the Bethe-Salpter framework is employed to calculate the exclusive production ratio of the neutral over charged Kaon pair in $e^{+}{e}^{-}$ annihilation continuum region for center of mass energies smaller than the $J/\Psi$ mass. The valence quark charge plays the key rôle. The cancellation of the diagrams for the same charge case (in $K_S+K_L$) and the non-cancellation of the diagrams for the different charge case (in $K^{-}+K^{+}$) lead to the ratio as $(m_s-m_d{)}^2/M_{Kaon}^2\sim 1/10$.
