Summary

We shall present results for the exclusive production
of \pi^{+} \pi^{-} and K^{+}K^{-} pairs mediated by Pomeron and Reggeon
exchanges, which constitute an irreducible background to resonance states
(e.g. f_{0}(980), f_{2}(1270), f_{0}(1500), \chi_{c0}).
We include absorption effects due to proton-proton interaction,
pion/kaon rescattering and discuss differences between vectorial and
tensorial
Pomeron for exclusive diffractive production of mesons.
We compare the results with the existing experimental data
and present predictions for the RHIC, Tevatron and LHC colliders.
