The Glauber model and its Monte Carlo (MC) implementations are indispensable tools for interpreting relativistic heavy-ion collisions, particularly given the growing interest in extracting nuclear structure information from high-energy collision data. However, several unresolved conceptual challenges persist regarding the detailed mapping between nuclear deformation and the geometry of the collision fireball. The original derivation of Glauber used a factorized form of nuclear wave function—an assumption that breaks down for deformed nuclei, where nucleons exist in highly entangled quantum states. Using a toy model that includes quantum superposition of deformed nuclear wave functions across all possible orientations, we illustrate key differences between the full Glauber calculation and the traditional MC Glauber models, and estimate the impacts on both inelastic and elastic cross sections. Building on these results, we propose methodological improvements to MC Glauber simulations for collisions involving deformed nuclei and are working towards a pathway to integrate nuclear structure calculations into high-energy collision modeling.
