abstract
This is a review of the theoretical background, experimental techniques, and phenomenology of what is called the "Glauber Model" in relativistic heavy ion physics. This model is used to calculate "geometric" quantities, which are typically expressed as impact parameter (b), number of participating nucleons (N_part) and number of binary nucleon-nucleon collisions (N_coll). A brief history of the original Glauber model is presented, with emphasis on its development into the purely classical, geometric picture that is used for present-day data analyses. Distinctions are made between the "optical limit" and Monte Carlo approaches, which are often used interchangably but have some essential differences in particular contexts. The methods used by the four RHIC experiments are compared and contrasted, although the end results are reassuringly similar for the various geometric observables. Finally, several important RHIC measurements are highlighted that rely on geometric quantities, estimated from Glauber calculations, to draw insight from experimental observables. The status and future of Glauber modeling in the next generation of heavy ion physics studies is briefly discussed.

Rotational symmetry restoration in even-even nuclei generates an effective collision geometry that acts as a low-pass filter exponentially suppressing deformation modes, recovering the classical rigid-rotor limit only for large angular-momentum fluctuations.
Alpha clustering in 16O and 20Ne suppresses initial spin fluctuations in relativistic collisions, with a scaled ratio of fluctuations between the two systems proposed as a probe of cluster geometry.
First measurements of v_n (n=2-4) in 5.36 TeV O+O and Ne+Ne collisions show enhanced v2 in central neon collisions consistent with prolate nuclear deformation.
ATLAS observes increasing dijet imbalance with centrality in O+O and Ne+Ne collisions at 5.36 TeV, consistent with medium-induced energy loss in small systems.
New measurements of isolated, non-isolated, and inclusive J/ψ yields, nuclear modification factors, and fractions up to 60 GeV in pp and Pb+Pb collisions at 5.02 TeV.
ATLAS measures charged-particle pseudorapidity density and mean transverse momentum in O+O and Ne+Ne collisions at 5.36 TeV as a function of centrality and eta.
ATLAS reports significant suppression (I_AA < 1) of photon-tagged two-jet yields in Pb+Pb versus pp collisions at 5.02 TeV across three observables, compared to JEWEL, JETSCAPE, and LBT models.
Suppression of recoil jet yields and intra-jet broadening is observed in central Ru+Ru and Zr+Zr collisions, indicating medium-induced partonic energy loss.
Suppression of high-pT hadrons in peripheral Pb+Pb collisions is predominantly driven by initial-state geometric bias rather than final-state jet quenching.
Volume variation with multiplicity in ultracentral collisions is small when total entropy scales with nuclear mass number, as shown by relating it to initial density fluctuation profiles.
Charm quark production from the pre-equilibrium phase contributes non-negligibly to the total yield in heavy-ion collisions and may allow inference of pre-equilibrium properties when combined with better initial-state calculations.
Updated tabulated interstellar fluxes of antiprotons and antideuterons from weak-scale DM are provided using new propagation schemes and inelastic cross-sections, showing greater robustness than prior calculations.
Comparative analysis of published jet quenching data shows radius dependence differs between single-jet and dijet selections and between experiments, but fractional energy loss S_loss reduces sensitivity to the pp spectral shape for cross-experiment comparisons.
