TL;DR

This paper reformulates Glauber theory for nucleus-nucleus scattering to extend its applicability from high to intermediate energies, analyzing the validity of key approximations and comparing with conventional models.

Contribution

The paper introduces a new formulation of Glauber theory based on multiple scattering theory that works at intermediate energies, bridging a gap in existing models.

Findings

Validation of eikonal and adiabatic approximations at intermediate energies

Comparison shows the new theory aligns with conventional models under certain conditions

Discussion of in-medium effects on nucleon-nucleon interactions

Abstract

Glauber theory for nucleus-nucleus scattering at high incident energies is reformulated so as to become applicable also for the scattering at intermediate energies. We test validity of the eikonal and adiabatic approximations used in the formulation, and discuss the relation between the present theory and the conventional Glauber calculations with either the empirical nucleon-nucleon profile function or the modified one including the in-medium effect.
