摘要：The behaviour of the normalized variance of the multiplictiy distribution and the normalized
transverse momentum fluctuations with centrality is naturally explained by the dependence on
centrality of the number of clusters of color sources. This dependence predicts a nonmonotonic
behaviour with centrality of the multiplicity associated to high pT events. The clustering of color
sources is also able to reproduce the increase with centrality of the forward-backward long-range
correlations and its supression compared to superposition model predictions.
