Top-Quark p(T)-Spectra at LHC and Flavor Independence of z-Scaling
Original language description
New results of analysis of top-quark differential cross sections obtained by the CMS and ATLAS Collaborations in pp collisions at the LHC in the framework of z-scaling approach are presented. The spectra are measured over a wide range of collision energy root s = 7, 8, 13 TeV and transverse momentum p(T) = 30-1000 GeV/c of top-quark using leptonic and jet decay modes. The LHC data on transverse momentum of the top-quark spectra are compared with the Tevatron data obtained by the Dempty set Collaboration in p (p) over bar collisions at root s = 1.96 GeV. Flavour independence of the scaling function psi(z) in pp and p (p) over bar interactions over a wide collision energy range root s = 19 - 13000 GeV is verified. This property of psi(z) was found for different hadrons from pi-meson up to. particle. The flavour independence of psi(z) is used as indication on self-similarity of to p-quark production. A tendency to saturation of psi(z) at low z for top-quark is demonstrated. We anticipate that data on low-and high-p(T) inclusive spectra of top-quark production at LHC energies could be of interest for verification of the self-similarity over a wide range of masses and different flavour content of produced particles.
