Abstract

We argue that the energy dependence of the average position of the shower maximum, X_max, and of the number of produced muons, N_μ, can be explained by a change, around 10¹⁷eV, in the energy dependence of the inelasticity K, which decreases with the energy above the string percolation threshold.
