Exclusive $\phi$ production in proton-proton collisions in the resonance model

The exclusive $\phi$ meson production in proton-proton reactions is calculated within the resonance model. The considered model was already successfully applied to the description of $\pi$, $\eta$, $\rho$, $\omega$, $\pi\pi$ production in proton-proton collisions. The only new parameter entering into the model is the $\omega-\phi$ mixing angle $\theta_{mix}$ which is taken equal to $\theta_{mix} \approx 3.7^o$.
