Timelike electromagnetic kaon form factor

We compute the electromagnetic charged kaon form factor in time-like region by employing a Poincar\'e covariant formalism of Bethe-Salpeter equation to study quark-antiquark bound states conjunction with Schwinger-Dyson for quark propagator. Following recent kindred calculation pion factor, we include most relevant intermediate composite particles permitted their quantum numbers interaction kernel allow decay mechanism resonances involved. This term augments usual gluon mediated between quarks. For sufficiently low energy probing photon, is saturated $\rho(770)$ and $\phi(1020)$ resonances. assume $SU(2)$ isospin symmetry throughout. Our results absolute value squared agree qualitatively rather well quantitatively moderately so available experimental data.
