| Abstract: The production yields of leading charged-particle jets and charged particles in proton-proton collisionsare measured at $\sqrt{s} = 8$~TeV based on a data sample collected with the CMS detector and corresponding to an integrated luminosity of 45 $\mu$b$^{-1}$. The charged-particle jets (charged particles) are measured in the pseudorapidity range $|\eta|< 1.9\, (2.4)$ for transverse momenta $p_{\mathrm{T}} > 1\, (0.8)$~GeV. The measured yields integrated above a given minimum transverse momentum, $p_{\mathrm{T\,min}}$, provide information on the mechanism by which the underlying parton-parton cross sections are unitarised when approaching the low-$p_{\mathrm{T}}$ non-perturbative domain. Comparisons to predictions obtained from various Monte Carlo event generators, show that the measured observable has a large sensitivity to the underlying physics. | ||
