Alternative ansatz to wounded nucleon and binary collision scaling in high-energy nuclear collisions

Abstract

We introduce TRENTO, a new parametric initial condition model for high-energy nuclear collisions based on eikonal entropy deposition via a "reduced thickness" function. The model simultaneously describes experimental proton-proton, proton-nucleus, and nucleus-nucleus multiplicity distributions, and generates nucleus-nucleus eccentricity harmonics consistent with experimental flow constraints. In addition, the model is compatible with ultra-central uranium-uranium data unlike existing models that include binary collision terms.

6 pages, 5 figures. This version has a new title, significant revisions to the introduction and conclusion, and new figures 1-3. The presented model is available at https://github.com/Duke-QCD/trento
