Transverse Momentum and Pseudorapidity Spectrum of the Top Quark, Lepton, and b Jet in Proton-Proton Collisions at LHC

Abstract

We study the transverse momentum and pseudorapidity 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 nonextensivity of the process (n), and the width (σ) of pseudorapidity distribution, are extracted.
