Central exclusive production of $\eta$ and ${\eta }^{\prime }$ mesons in diffractive proton-proton collisions at the LHC and the nature of the pomeron

Piotr Lebiedowicz, Otto Nachtmann, Antoni Szczurek

Central exclusive production (CEP) of $\eta$ and ${\eta }^{\prime }$ mesons in proton-proton collisions at high-energies is discussed. At the LHC the main mechanism for the production of these meson…
