Exclusive diffractive resonance production in proton-proton collisions at high energies

TL;DR

This paper introduces a model for exclusive diffractive resonance production in high-energy proton-proton collisions, predicting distributions based on Pomeron interactions and resonance contributions, including the f0(500).

Contribution

It presents a novel model combining Pomeron distributions and resonance contributions to predict resonance production in proton-proton collisions.

Findings

Predicts double differential distributions up to 5 GeV mass region

Incorporates Pomeron and f trajectories in the model

Accounts for background and resonance dominance in the low-mass region

Abstract

A model for exclusive diffractive resonance production in proton-proton collisions at high energies is presented. This model is able to predict double differential distributions with respect to the mass and the transverse momentum of the produced resonance in the mass region $\sqrt{M^2}\le$5 GeV. The model is based on convoluting the Pomeron distribution in the proton with the Pomeron-Pomeron-meson total cross section. The Pomeron-Pomeron-meson cross section is saturated by direct-channel contributions from the Pomeron as well as from two different $f$ trajectories, accompanied by the isolated f$_0(500)$ resonance dominating the $\sqrt{M^{2}} \leq $ GeV region. A slowly varying background is taken into account.
