On Self-Similarity of Top Production at Tevatron

Popis výsledku v původním jazyce

Results of analysis of D{} 1.0 fb1 data on top-quark differential cross section measurements at the Fermilab Tevatron collider at s = 1960 GeV in the framework of z-scaling approach are presented. Flavour independence of the scaling function ?(z) observed in pp and pp interactions over a wide collision energy range s = 191960 GeV is veriˇed. This property of ?(z) was found for different hadrons from ? meson up to ? particle. The avour independence of ?(z) is used as indication to self-similarity of top-quark production. A tendency to saturation of ?(z) at low z for top-quark is demonstrated. The momentum fractions x1 of the incoming (anti)protons as a function of the scaled transverse momentum pT /m and masses of heavy mesons are studied. We anticipatethat data on low- and high-pT inclusive spectra of top-quark production at Tevatron and LHC energies could be of interest for veriˇcation of the self-similarity over a wide range of masses and different avour content of produced particle
