We show that the multiplicity distribution associated to high p T events is given in terms of the total multiplicity distribution in an universal way due to the fact that these events are self-shadowed. In particular, the mean associated multiplicity is related to the fluctuations on the multiplicity distribution. In the framework of percolation of strings these fluctuations are related to clus...

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 p T events. The clustering of color sources is also...

We argue that the shape of the system-size dependence of strangeness production in nucleus-nucleus collisions can be understood in a picture that is based on the formation of clusters of overlapping strings. A string percolation model combined with a statistical description of the hadronization yields a quantitative agreement with the data at √ s N N = 17.3 GeV. The model is also applied to RHI...

Similar to electromagnetic forces, strong interactions might induce such collective effects as Cherenkov and Mach waves. Their conical structure would be responsible for specific ring-like events. The theoretical and experimental arguments in favor of these phenomena are discussed and their most important features are described.
