CMS data at $\sqrt{s}=7\text{TeV}$  [17] for 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 MadGraph (MG), interfaced to pythia8 using CUETP$8$S$1$-CTEQ$6$L1 and CUETP$8$M$1$, and to powheg (PH), interfaced to pythia8 using CUETP$8$S$1$-HERAPDF1.5LO and CUETP$8$M$1$. The bottom panels of each plot show the ratios of these predictions to the data, and the green bands around unity represent the total experimental uncertainty
