Geometrical scaling and its breaking in high energy collisions

TL;DR

This paper analyzes data from high energy collisions to study Geometrical Scaling (GS), its underlying saturation momentum, and the conditions under which GS is maintained or broken across different energies and systems.

Contribution

It provides new insights into how Geometrical Scaling emerges and breaks in high energy collision data, emphasizing the role of saturation momentum.

Findings

Identification of conditions where GS holds or breaks

Relation of data across different energies and systems via saturation momentum

Insights into the energy dependence of GS breaking

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.
