TL;DR

This paper models the exclusive production of the $f_{1}(1285)$ meson in proton-proton collisions through pomeron-pomeron fusion, fitting parameters to experimental data and providing predictions for LHC experiments.

Contribution

It introduces two methods to construct the pomeron-pomeron-$f_{1}$ coupling within the tensor-pomeron framework and compares model predictions with experimental data and holographic QCD models.

Findings

Predictions provided for LHC experiments

Comparison with Sakai-Sugimoto model results

Abstract

Exclusive production of axial-vector $f_{1}(1285)$ meson in proton-proton collisions via pomeron-pomeron fusion within the tensor-pomeron approach is discussed. Two ways to construct the pomeron-pomeron-$f_{1}$ coupling are presented. We adjust the parameters of our model to the WA102 experimental data and compare with predictions of the Sakai-Sugimoto model. Predictions for LHC experiments are given.
