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