(a) Distribution of energy in ZNC in each 5\% centrality interval for events simulated using TGMC and for the experimental data. (b) Distribution of the asymmetry parameter $\alpha_{\rm{ZN}}$ in the simulated events and in experimental data for different centralities. For clarity, only 5 distributions are shown. The distributions corresponding to 20-25\% and 25-30\% lie between those of 15-20\% and 30-35\%. |
