Light Hadron Production in Proton-Proton Collisions at Different LHC Energies: Measured Data versus a Model

TL;DR

This paper analyzes proton-proton collision data at LHC energies, comparing measured transverse momentum spectra and ratios of light hadrons with predictions from a Sequential Chain Model, finding modest agreement.

Contribution

It introduces a comparison of experimental data with a specific version of the Sequential Chain Model for light hadron production at multiple LHC energies.

Findings

Modest agreement between data and model predictions.

Analysis of pT spectra for pions, kaons, protons.

Evaluation of ratio-behaviors of light hadrons.

Abstract

Experiments involving proton-proton collisions at energies $\sqrt{s_{NN}}$ = 0.9, 2.76 and 7 TeV in Large Hadron Collider (LHC) have produced a vast amount of high-precision data. Here, in this work, we have chosen to analyse the two aspects of the measured data, viz., (i) the $p_T$ -spectra of pions, kaons, proton-antiproton at above-mentioned energies, and (ii) some of their very important ratio-behaviours, in the light of a version of the Sequential Chain Model (SCM). The agreements between the measured data and model-based results are generally found to be modestly satisfactory.
