“…Proposals to study collisions with 16 O beams at the LHC [8] and at RHIC [9] are presently under serious consideration. In this regard we have carried out an analysis of the initial state in 16 O- 16 O in the Monte Carlo Glauber approach [10]. Similar results in other models were presented earlier in [11,12].…”

In this talk we discuss several interesting aspects of collective flow in small systems in reference to planned future experiments. First, we bring in the novel possibility of exploring elliptic flow with heavy nuclei collisions on polarized deuteron targets, accessible in AFTER@LHC program after Long Shutdown 3. Then we pass to the Glauber model predictions for the presently considered 16 O − 16 O program and RHIC and the LHC. Finally, we turn to our previous proposal concerning specific flow signatures of intrinsic correlations (such as the supposed α clusterization) in the structure of light nuclei in collisions with heavy nuclei. In particular, 12 C-heavy nucleus ultrarelativistic reactions would provide insight into the ground-state 12 C structure, complementary to the traditional nuclear structure features.

“…Indeed, the 16 nucleons in oxygen tend to group together in four α-particles, which potentially has important consequences for the shape of the geometry. For this reason, for O we randomly rotate a sampled oxygen nucleus from a list of 6000 O configurations computed using effective two-and three-nucleon potentials, which is able to capture these correlations [19][20][21]. The difference between a standard Woods-Saxon distribution and the α-clustered version has recently been studied in [21,22].…”

We introduce a global analysis of relativistic heavy ion collisions using Trajectum of a significantly higher precision and including a new option to vary the normalization of the centrality estimator. We use the posterior distribution of our parameters to generate a set of high statistics samples that allows us to make precise predictions including statistical and systematic uncertainties estimated from the model parameter distribution. The results are systematically compared with experiment whereby we also include many observables not included in the global analysis. This includes in particular (extremely) ultracentral anisotropic flow and mean transverse momentum, whereby we find satisfactory agreement with experiment where data is available. Lastly, we compute spectra and anisotropic flow for oxygen-oxygen collisions performed at RHIC and to be performed at the LHC and comment on how these collisions may inform us on properties of the Quark-Gluon-Plasma.

“…This approach has been exploited already with great success in the context of small-system geometry engineering by the PHENIX collaboration [33][34][35][36][37][38][39][40]. More recently, dedicated runs of 16 O 16 O collisions have been proposed [22,[41][42][43][44][45][46][47] at both RHIC and LHC as a way of extending the geometry scan results to systems of intermediate size, which exhibit more exotic initial configurations due to an effect known as "α-clustering".…”

“…In such nuclei, nucleon positions are not completely uncorrelated, but tend to cluster together into groupings of two neutrons and two protons each, thereby effectively forming α particles (or "α clusters") in the nucleus. These correlations lead to quantifiable effects on the initial states of collisions between such nuclei and may manifest themselves in corresponding precision measurements of nuclear collision flow observables [44,48]. It may also be possible to have subnucleonic fluctuations that would influence the collective flow [49][50][51][52][53][54][55].…”

Collisions of light and heavy nuclei in relativistic heavy-ion collisions have been shown to be sensitive to nuclear structure. With a proposed 16 O 16 O run at the LHC and RHIC we study the potential for finding α clustering in 16 O. Here we use the state-of-the-art iEBE-VISHNU package with 16 O nucleonic configurations from ab initio nuclear lattice simulations. This setup was tuned using a Bayesian analysis on pPb and PbPb systems. We find that the 16 O 16 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 α-clustering, nucleonic, and subnucleonic degrees of freedom in the initial state.
