Fluctuations and the clustering of color sources

Abstract

We present our results on multiplicity and $p_T$ fluctuations at LHC energies in the framework of the clustering of color sources. In this approach, elementary color sources -strings- overlap forming clusters, so the number of effective sources is modified. We find that the fluctuations are proportional to the number of those clusters.
