Central exclusive diffractive production of axial-vector $f_1$ mesons in proton-proton collisions

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.
