Partonic Entropy of the Proton and DGLAP Evolution

This paper explores the concept of partonic entropy within the context of proton structure, using the DGLAP evolution scheme. The key finding is that this entropy increases with the evolution scale, suggesting a growing complexity in the proton's internal structure as probed at higher energy scales. The paper also touches upon the importance of saturation effects at small x and proposes a connection between partonic entropy and entanglement entropy, potentially offering a new observable for experimental verification.
