Strange Vector Form Factor of Kaons

Abstract

Starting from the $ω$-$ϕ$ mixing, further assuming the coupling of the quark-current of some flavour to be of universal strenth exclusively to the component of vector-meson wave function with the same flavour and finally taking numerical values of the coupling constant ratios $(f_{ωK \bar K}/f_ω^e)$, $(f_{ϕK\bar K/f_ϕ^e)$ from the isoscalar part of a realistic six-resonance unitary and analytic model of the kaon electromagnetic structure, the strange-quark vector current form factor behaviour of K-mesons in space-like and time-like regions is predicted.
