Abstract
We study the transverse momentum and pseudorapidity spectrum of the top quark and their decay products, the t t ¯ 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 nonextensivity of the process ( n ), and the width ( σ ) of pseudorapidity distribution, are extracted.
Highlights
The top quark is an interesting particle
We use the Tsallis-Pareto-type function [4, 5] and the three-source Landau hydrodynamic model [6] to describe the transverse momentum and pseudorapidity spectra of the top quark, lepton, and bottom quark produced in proton-proton collisions at the center of mass energy pffiffi s = 13 TeV measured at the parton level and particle level, in the full phase space and in the fiducial phase by CMS Collaboration at the Large Hadron Collider (LHC) [7]
In a lot of models and formulas, the Tsallis-Pareto-type function is a good choice for transverse momentum spectra
Summary
The top quark is an interesting particle. It was first found by the Tevatron detector of Fermi National Accelerator Laboratory in 1995 [1,2,3]. Its biggest mass is one of the hotspots for physicists It is the only one quark which will decay before it becomes hadron. Many models and functions are used to describe the transverse momentum and pseudorapidity spectra. We use the Tsallis-Pareto-type function [4, 5] and the three-source Landau hydrodynamic model [6] to describe the transverse momentum and pseudorapidity spectra of the top quark, lepton, and bottom quark produced in proton-proton (pp) collisions at the center of mass energy pffiffi s = 13 TeV measured at the parton level and particle level, in the full phase space and in the fiducial phase by CMS Collaboration at the LHC [7].
