The inner slope of the mass density profile of clusters of galaxies.

I will present observational determinations of the inner slope of the cluster mass density profiles based on data from the CLASH-VLT/Zooming collaboration (P.I.: Piero Rosati). Our results show remarkable consistency with cosmological numerical simulation predictions based on the LambdaCDM model, at variance with previous observational results that claimed a much flatter inner density profile. I will discuss the reason for this difference and present prospects for future developments on this topic.
