  "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 $\\sqrt{s} = 29.1$ GeV. We present cross sections and differential distributions for the LHC energy of $\\sqrt{s} = 13$ TeV. For $pp \\to pp η$, the upper limit of the total cross section is 2.5 $μ$b for $|η_{M}| < 1$ and 5.6 $μ$b for $2 < η_{M} < 5$. For $pp \\to pp η'$, the predicted cross sections are 0.3--0.7 $μ$b and 0.9--2.1 $μ$b 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.",
