Collisions of light and heavy nuclei in relativistic heavy-ion collisions have been shown to be sensitive to nuclear structure. With a proposed $^{16}\mathrm{O}^{16}\mathrm{O}$ run at the LHC and RHIC we study the potential for finding $\alpha$ clustering in $^{16}$O. Here we use the state-of-the-art iEBE-VISHNU package with $^{16}$O nucleonic configurations from {\rm ab initio} nuclear lattice simulations. This setup was tuned using a Bayesian analysis on pPb and PbPb systems. We find that the $^{16}\mathrm{O}^{16}\mathrm{O}$ system always begins far from equilibrium and that at LHC and RHIC it approaches the regime of hydrodynamic applicability only at very late times. Finally, by taking ratios of flow harmonics we are able to find measurable differences between $\alpha$-clustering, nucleonic, and subnucleonic degrees of freedom in the initial state.

  1. Initial spin fluctuations as a probe of cluster spin structure in $^{16}\mathrm{O}$ and $^{20}\mathrm{Ne}$ nuclei

    nucl-th 2025-12 unverdicted novelty 7.0

    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.

  2. Data-driven method to estimate contamination from light ion beam transmutation at colliders

    physics.acc-ph 2025-09 unverdicted novelty 6.0

    A data-driven method is introduced to quantify contamination effects from light-ion beam transmutation using time-dependent control regions and a simple illustrative model.

  3. Event-by-event fluctuations of elliptic flow in ultrarelativistic O+O collisions

    nucl-th 2026-06 unverdicted novelty 5.0

    In O+O collisions, initial eccentricity and elliptic flow are fluctuation-driven and can be reproduced from a small set of uncorrelated modes.

  4. Equilibrated fraction of QCD matter in high-energy oxygen--oxygen collisions

    nucl-th 2026-04 unverdicted novelty 5.0

    The equilibrated core in O+O collisions overtakes the nonequilibrium corona above midrapidity multiplicity of about 20, yet corona contributions persist in central events, making pure hydrodynamics inadequate.
