What can we learn from the Caldwell plot?

TL;DR

This paper demonstrates that including screening corrections aligns the derivative of the structure function with pQCD expectations and explains the Caldwell plot's previously puzzling behavior.

Contribution

It shows that screening corrections resolve the Caldwell plot enigma, providing a clearer understanding of the structure function's behavior in QCD.

Findings

Screening corrections reconcile data with pQCD predictions

The Caldwell plot's anomaly is explained by these corrections

Derivative of F2 aligns with theoretical expectations when corrections are included

Abstract

We show that when screening corrections are included $ \frac{\partial F_{2}(x,Q^{2})}{\partial \ln Q^{2}}$ is consistent with the behaviour that one expects in pQCD. Screening corrections explain the enigma of the Caldwell plot.
