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 $t\overline{t}$ 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 ( $\sigma$ ) of pseudorapidity distribution, are extracted.
