Comparison of the results from the evolution of the $d{n}_{\mathrm{ch}}/d\eta$ with dependence in pseudorapidity from Eq. (13) for $pp$ collisions at different energies (lines); data are taken from Refs. [13, 14, 15].Reuse & Permissions

Comparison of the results from the evolution of the $d{n}_{\mathrm{ch}}/d\eta$ with pseudorapidity from Eq. (12) for Cu-Cu collisions at 22.4-, 62.4-, and 200-GeV energies; data are taken from Ref. [16]. Error bars in color blue, green, pink, red, purple, and black are used for the corresponding centralities $45\%$–$55\%$, $35\%$–$45\%$, $25\%$–$35\%$, $15\%$–$25\%$, $6\%$–$15\%$, $0\%$–$6\%$, respectively; lines in black show our results.Reuse & Permissions

Comparison of the results from the evolution of the $\frac{d{n}_{\mathrm{ch}}}{d\eta }\frac{1}{(N_{\mathrm{part}}/2)}$ with the pseudorapidity from Eq. (12) for Pb-Pb collisions at 2.76 TeV; data are taken from [18]. Error bars in color green, blue, pink, and red are used for the corresponding centralities $85\%$–$95\%$, $50\%$–$55\%$, $0\%$–$90\%$, and $0\%$–$5\%$, respectively; lines in black are the corresponding results from the model to the respective centrality. For the smaller centrality we use the number of participants corresponding to 85$\%$–95$\%$ shown in the dot- dashed line; dashed line is the minimum number of participants equal to 2.Reuse & Permissions
