Using geometric scaling and Glauber-Gribov nuclear gluon distributions, the authors find that the QCD dynamical entropy in proton-nucleus collisions is essentially independent of the atomic mass number A, while the entropy density scales with the nuclear cross-sectional area.

abstract
We derive analytical results for unintegrated color dipole gluon distribution function at small transverse momentum. By Fourier transforming the $S$-matrix for large dipoles we derive the results in the form of a series of Bells polynomials. Interestingly, when resumming the series in leading log accuracy, the results showing up striking similarity with the Sudakov form factor with role play of coupling is being done by a constant that stems from the saddle point condition along the saturation line.

Investigating QCD Dynamical Entropy in high-energy nuclear collisions
Using geometric scaling and Glauber-Gribov nuclear gluon distributions, the authors find that the QCD dynamical entropy in proton-nucleus collisions is essentially independent of the atomic mass number A, while the entropy density scales with the nuclear cross-sectional area.
