Top-Quark p(T) - Spectra at CMS and Flavor Independence of z - Scaling

Original language description

We present new results of analysis of top-quark differential cross sections obtained by the CMS Collaboration in pp collisions in the framework of the z-scaling approach. The spectra are measured over a wide range of collision energy root s = 7, 8, 13 TeV and transverse momentum p(T) = 30-500 GeV/c of top-quark using leptonic and jet decay modes. Flavor independence of the scaling function psi(z) is verified in the new kinematic range. The results of analysis of the top-quark spectra obtained at the LHC are compared with similar spectra measured in (p) over barp collisions at the Tevatron energy root s = 1.96 TeV. A tendency to saturation of psi(z) for the process at low z and a power-law behavior of psi(z) at high z is observed. The measurements of high-p(T) spectra of the top-quark production at highest LHC energy is of interest for verification of self-similarity of particle production, understanding flavor origin and search for new physics symmetries with top-quark probe.
