TL;DR

This paper extends a Pomeron model for soft high energy scattering to include single inclusive cross sections, successfully reproducing existing data and providing predictions for future LHC measurements.

Contribution

The paper introduces an extension of the two component Pomeron model to include semi enhanced Pomeron-particle vertex corrections for better description of inclusive cross sections.

Findings

Model accurately fits data from 200-1800 GeV energies.

Predictions made for LHC energy range.

Supports validity of the Pomeron model approach.

Abstract

We extend our two component Pomeron model (GLMM) for soft high energy scattering to single inclusive cross sections. We present a suitable formulation which also includes the semi enhanced Pomeron-particle vertex corrections. The available data on single inclusive density $(1/\sigma_{in})d\sigma/dy$ in the c.m. energy range of 200-1800 GeV, including the just published Alice Collaboration point at 900 GeV,and the CMS collaboration measurements at 900 and 2360 GeV are well reproduced by our model. We also present predictions covering the complete LHC energy range which can be readily tested in the early low luminosity LHC runs. The results presented in this communication provide additional support to our Pomeron model approach.
