CDF data at $\sqrt{s}=1.96\text{TeV}$ [11] on the particle (top) and $p_{\mathrm{T}}^{\mathrm{sum}}$ densities (bottom) for charged particles with $p_{\mathrm{T}}>0.5\text{GeV}$ and $|\mathit{\eta }|<0.8$ in the TransMIN (left) and TransMAX (right) regions as defined by the leading charged particle, as a function of the transverse momentum of the leading charged-particle $p_{\mathrm{T}}^{\max }$. The data are compared to the pythia6 Tune Z$2^{\ast }$lep, CUETP$6$S$1$-CTEQ$6$L1 and CUETP$6$S$1$-HERAPDF1.5LO. The green bands in the ratios represent the total experimental uncertainties
