Flavour independence of the scaling function ψ(z) observed in pp and pp¯ interactions over a wide collision energy range √ s = 19−1960 GeV is veriˇed. This property of ψ(z) was found for different hadrons from π meson up to Υ particle. The avour independence of ψ(z) is used as indication to self-similarity of top-quark production. A tendency to saturation of ψ(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 anticipate that 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 particles.
