Central exclusive production of axial-vector $f_{1}$ mesons in proton-proton collisions

TL;DR

This paper investigates the production mechanisms of axial-vector $f_1$ mesons in proton-proton collisions through pomeron-pomeron fusion, comparing theoretical models with experimental data and providing predictions for future collider experiments.

Contribution

It introduces two models for the pomeron-pomeron-$f_1$ coupling and offers predictions for RHIC and LHC based on these models.

Findings

Comparison with WA102 data shows model viability.

Predictions for $f_1$ production at RHIC and LHC.

Insights into pomeron-pomeron-$f_1$ interaction mechanisms.

Abstract

The production of $f_{1}$ ($J^{PC} = 1^{++}$) mesons in proton-proton collisions via pomeron-pomeron fusion is discussed. Two ways to construct the pomeron-pomeron-$f_{1}$ coupling are presented. Comparisons with data from the WA102 experiment are made and predictions for RHIC and LHC experiments are given.
