Central exclusive production of η and η' mesons in diffractive proton-proton collisions at the LHC
Abstract
We discuss central exclusive production (CEP) of η and η'(958) mesons in high-energy proton-proton collisions using the tensor-pomeron approach, incorporating absorption effects at the amplitude level. Model parameters are constrained using WA102 experimental data measured at √s = 29.1 GeV. We present cross sections and differential distributions for the LHC energy of √s = 13 TeV. For pp → pp η, the upper limit of the total cross section is 2.5 μb for |ηM| < 1 and 5.6 μb for 2 < ηM < 5. For pp → pp η', the predicted cross sections are 0.3--0.7 μb and 0.9--2.1 μb in the respective pseudorapidity regions. These results demonstrate the feasibility of studying diffractive flavour singlet pseudoscalar meson production to probe the nature of the pomeron at the LHC.
