Geometrical scaling and its breaking in high energy collisions

Abstract

We report on recent analyses of different pieces of data, which exhibit Geometrical Scaling (GS) and its breaking. GS is a consequence of the existence of an intermediate energy scale, called saturation momentum, and allows to relate data at different energies, of different systems and also at different multiplicities and/or centralities.
