Summary:Similarly to the electromagnetic pseudoscalar-meson transition form factors one can define also strange-quark vector current pseudoscalar-meson transition form factors, contributing only to a behaviour of the isoscalar parts of the previous ones. Their explicit form is found by constructing unitary and analytic models of the strange pseudoscalar-meson transition form factors dependent only on \(\omega\) and \(\phi\) coupling constant ratios as a free parameters. Numerical values of these ratios are then determined from the corresponding pseudoscalar-meson transition form factors by employing the \(\omega\)-\(\phi\) mixing and a special assumption on the coupling of the quark components of vector-meson wave functions to flavour component of currents under consideration.
