Resonance production in Pomeron-Pomeron collisions at the LHC

TL;DR

This paper develops a theoretical model for Pomeron-Pomeron total cross sections in the resonance region at the LHC, incorporating Regge poles, f trajectories, and the f0(500) resonance to aid in predicting exclusive resonance production.

Contribution

It introduces a novel Regge pole-based model for Pomeron-Pomeron interactions, including the f0(500) resonance, for the first time in this context.

Findings

Provides a detailed Pomeron-Pomeron cross section model up to 5 GeV.

Incorporates the f0(500) resonance explicitly.

Offers a key theoretical input for LHC resonance production calculations.

Abstract

A model for Pomeron-Pomeron total cross section in the resonance region $\sqrt{M^{2}} \le$ 5 GeV is presented. This model is based on Regge poles from the Pomeron and two different $f$ trajectories, and includes the isolated f$_{0}(500)$ resonance in the region $\sqrt{M^{2}}\lesssim 1$ GeV. A slowly varying background is included. The presented Pomeron-Pomeron cross section is not directly measurable, but is an essential ingredient for calculating exclusive resonance production at the LHC.
