摘要: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.
