QCD Wehrl and Entanglement Entropies in Gluon Spectator Model
Analysis
This paper explores the use of Wehrl entropy, derived from the Husimi distribution, to analyze the entanglement structure of the proton in deep inelastic scattering, going beyond traditional longitudinal entanglement measures. It aims to incorporate transverse degrees of freedom, providing a more complete picture of the proton's phase space structure. The study's significance lies in its potential to improve our understanding of hadronic multiplicity and the internal structure of the proton.
Key Takeaways
- •Investigates Wehrl entropy as a measure of entanglement in the proton.
- •Uses the Husimi distribution derived from the Wigner distribution.
- •Includes transverse degrees of freedom, providing a more complete picture.
- •Shows entanglement entropy emerges from the Husimi distribution's normalization.
Reference
“The entanglement entropy naturally emerges from the normalization condition of the Husimi distribution within this framework.”
