Table 4.

The pythia6 parameters, tuning range, Tune Z2lep values [31], and best-fit values for CUETP6S1-CTEQ6L1 and CUETP6S1-HERAPDF1.5LO, obtained from fits to the TransMAX and TransMIN charged-particle and pTsum densities as defined by the pTmax of the leading charged particle at s=0.3 , 0.9, 1.96, and 7TeV
