Central exclusive production of $K^{+}{K}^{-}$ pairs in proton-proton collisions

Abstract

We discuss central exclusive diffractive production of light mesons in the reactions $pp\to pp{\pi }^{+}{\pi }^{-}$ and $pp\to pp{K}^{+}{K}^{-}$. The calculation is based on a tensor-pomeron approach. We include a purely diffractive dipion continuum, and the scalar $f_0(980)$, $f_0(1500)$, $f_0(1710)$ and tensor $f_2(1270)$, $f_2^{\prime }(1525)$ resonances decaying into pseudoscalar meson pairs. We include also photoproduction mechanisms for the nonresonant (Drell-Söding) and the $\varphi (1020)$ resonance contributions. The theoretical results are compared with existing CDF experimental data and predictions for being carried out LHC experiments are presented. The distributions in dimeson invariant mass and in a special "glueball filter variable" including the interference effects of resonance and dimeson continuum are presented.
