Geometric Scaling from GLAP evolution
Fabrizio Caola, Stefano Forte
TL;DR
This paper demonstrates that geometric scaling observed in virtual photon-proton cross section data can be explained by standard linear GLAP evolution, identifying regions where saturation effects might be evident.
Contribution
It shows that geometric scaling can be derived from linear GLAP evolution with generic boundary conditions, clarifying the conditions for parton saturation evidence.
Findings
Geometric scaling explained by linear GLAP evolution.
Identification of kinematic regions indicating potential saturation.
Validation of scaling behavior across a wide kinematic range.
Abstract
We show that the geometric scaling of the total virtual photon-proton cross section data can be explained using standard linear GLAP perturbative evolution with generic boundary conditions in a wide kinematic region. This allows us to single out the region where geometric scaling may provide evidence for parton saturation.
