Description
We examine symmetric and asymmetric cumulants as well as rapidity-even dipolar flow in ${}^{16}$O+${}^{16}$O collisions at $\sqrt{s_{NN}} = 200$~GeV to explore $\alpha$-clustering phenomena in light nuclei within the viscous relativistic hydrodynamics framework. Imprints of $\alpha$-clustering manifest in the anisotropic flow coefficients and their correlations---particularly in observables involving elliptic-triangular flow correlations. Our results indicate that the final-state symmetric and asymmetric cumulants---especially $\mathrm{NSC}(2,3)$ and $\mathrm{NAC}_{2,1}(2,3)$---are sensitive to the initial nuclear geometry. Moreover, our results reveal a significant difference in rapidity-even dipolar flow, $v_1^{\text{even}}$, between $\alpha$-clustered and Woods--Saxon configurations in high-multiplicity events. These results highlight the crucial influence of nuclear structure on heavy-ion collision dynamics and offer observables to differentiate nuclear geometries, especially in ultra-central collisions.
