TL;DR

This paper analyzes the transverse momentum and rapidity spectra of top quarks and their decay products in 13 TeV proton-proton collisions using statistical models, extracting key physical parameters.

Contribution

It introduces a combined use of Tsallis-Pareto and Landau hydrodynamic models to describe top quark spectra and extract relevant physical parameters in high-energy collisions.

Findings

Parameters like temperature and non-extensivity are quantitatively determined.

The models successfully fit the experimental spectra.

Insights into the particle production mechanism at 13 TeV are provided.

Abstract

We study the transverse momenta and (pseudo)rapidity spectrum of the top quark and their decay products, the tt-system, and the total number of jets in proton-proton (pp) collisions at 13 TeV by using the Tsallis-Pareto-type function and the three-source Landau hydrodynamic model, respectively. The related parameters, such as the effective temperature of the interacting system (T), the non-extensivity of the process (n) and the width ($\sigma$) of (pseudo)rapidity distribution are extracted.
