You can see a gradual scale breaking feature in the fragmentation region. Pseudo-rapidity distribution of all particles. Therefore we show only a few examples here. The number of simulated events is 3000. The number of simulated events is 3000.
Circles are the experimental data.
This comparison is wrong. We should be careful of this comparison, because the experimental data has some bias while the Monte-Carlo data has no such bias. Although the agreement is good, we should not rely on this agreement too much. The meaning of this data is explained by this diagram. .
